Definitions

  • This invention relates to a system for handling biological specimens. More particularly, the present invention provides a system for labelling and tracking medical specimens from the collection stage to the point of testing.
  • the next step normally involves obtaining the necessary specimen or specimens from a patient.
  • the patient attends the doctor's office or medical testing facility and gives the laboratory technician the necessary patient data and then the appropriate specimen(s).
  • the specimen is packaged and labelled according to the patient data and testing which is to be done.
  • the specimen is then tested as required by trained laboratory technicians.
  • the process of collecting the patient data and labelling the specimen(s) is usually time consuming and inefficient.
  • Testing is typically performed in specialized testing laboratories which are capable of handling a large number of specimens on any one day. Depending on the type of analysis requested by the doctor, the specimens can be tested individually or as part of a batch testing process. In addition, certain tests are automated and done by machines which are commercially available, for example, a KODAK (trade mark) analyzer. On any one day, there can be thousands of specimens undergoing a multitude of tests in a laboratory facility. Since the laboratory facility is usually separate from the place where the patient gave the specimen(s), the collecting, routing and tracking of the specimens is very important to ensure that the specimens are tested as requested by the doctor, and that the test results are reported to the correct originating doctor/patient and that urgent tests are given priority.
  • KODAK trade mark

  • the system 1 includes a central computer 10, at least one network printer 12, and a number of remote computer terminals 14.
  • the remote terminals 14 are coupled to the central computer 10 through a communication network indicated by reference 16.
  • the central computer 10 includes a memory storage disk 18.
  • the disk 18 provides mass storage for patient files as will be explained in detail below.
  • each computer terminal 14 comprises a display monitor 20 and a data entry device such as a keyboard 22.
  • the computer terminal 14 also includes a card reader 24 and a bar ⁇ code scanner 26.
  • the computer terminal 14 can also be connected to a local or slave printer 28.
  • the card reader 24 is used to input data from a patient identification card 30.
  • the identification card 30 can comprise a health plan card such as the Ontario Health Card for example which is issued to all members of the Ontario Provincial Health Care Plan, or it can be an appropriate insurance plan health card.
  • the patient identification card 30 includes a magnetic strip 32 which stores electronically encoded information pertaining to the patient.
  • the magnetic strip 32 provides a quick and effective method for entering patient data into the system 1. As will be discussed in detail, scanning the patient identification card 30 is usually the first step in generating a requisition file for the patient.
  • patient identification cards can be issued and administered under the authority of the testing laboratory. These cards can be further tailored to the operation of the system 1 by including additional patient information such as date of birth, patient's telephone number, physician's name and telephone number (which information is not on, for example, the Ontario Health Card).
  • the bar-code scanner 26 is used to input test requests which are represented by a series of bar-codes on a test code template 34.
  • the test code template 34 is sheet which includes a list of bar-codes, each bar-code corresponding to a test.
  • the scanner 26 allows test requests to be quickly and accurately read from the test code template 34.
  • the scanner 26 can be any commercially available light pen such as those available from Symbol Technologies Inc.
  • the keyboard 22 is available for entering any additional information which is not included on the patient identification card 30 or on the test code template 34. To facilitate order entry, the additional information, for example the client number (physician identification codes - see below), can also be encoded as bar-codes on a separate template (not shown) and read using the scanner 26.
  • the system 1 includes two types of printers. They are the network printer 12 and the local printer 28.
  • the primary function of the printers 12 and 28 is to print an assortment of labels 36.
  • the labels are used for identifying, routing and tracking the medical specimens from the time of collection from the patient to the point of testing in the laboratory.
  • the network printer 12 is accessible by the central computer 10 or any of the computer terminals 14 through the network 16 but may not be adjacent or close to the laboratory technician who is preparing the order entry.
  • the local or slaved printer 28 on the other hand, is dedicated to a particular computer terminal 14 and provides the laboratory technician with immediate access to the printed labels.
  • a suitable commercially available device for both the network and local printers 12, 28 is the Prodigy Label (trade mark) printer which is manufactured by the Fargo Electronic Inc. of Minnesota. Requests for printing on the network printer 12 are typically queued and submitted as batch jobs under the control of the central computer 10. Therefore, the turn-around time for printing labels can vary depending on the number of print jobs submitted from the computer terminals 14. Since the local printers 28 are dedicated or slaved to the computer terminals 14, the labels 36 can usually be printed within seconds of the print request. The local printers 28 also provide the laboratory technician with immediate access to the printed labels.
  • FIG. 2 shows in flow chart form an overview of the operation of the system 1.
  • the patient Upon arrival at a testing laboratory, the patient is greeted by the laboratory technician or a receptionist (indicated by block 200). Before a specimen is taken from the patient, an order must be entered in the system 1. Order entry involves taking the patient's health card and also taking the requisition form from the patient (step 202).
  • the requisition form is typically a paper form which lists the tests requested by the patient's doctor.
  • the patient's identification card 30 is scanned for patient data.
  • the patient identification card 30 includes the patient's health card number, the patient's name and age, and the version code for the health card.
  • the health card number provides a unique code which is exploited by the system 1 to store and retrieve data for a particular patient. It will be appreciated by those skilled in the art that using known techniques additional patient data can be encoded in the magnetic strip 32 contained on the identification card 30 ( Figure 1).
  • the system 1 determines if the patient is a recurring patient (step 206), that is whether the patient has been previously tested by the laboratory. If the patient is not a return or recurring patient, then additional information must be entered in step 208 to complete the order entry.
  • the additional information can include the following: date of birth; physician's name; physician's telephone number; physician's identification number (i.e. client number); additional (i.e. carbon copied) physicians' names and their client numbers; patient location (e.g. nursing home or hospital); requisition date; billing and accounting information; source of specimen, e.g. urine or swab. Further information may be needed at this step 208 depending on the type of testing which is to be performed.
  • the additional information is entered into the system 1 by the laboratory receptionist using the keyboard 22 and the display monitor 20 ( Figure 1) or the scanner 26 for client numbers on a code template. Once the all the information has been entered, the system 1 will generate a patient file which is indexed under the patient's health card number and stored on the disk 18 ( Figure 1) and thereby becomes a recurring patient file as explained below. If the patient is a recurring or return patient, then in step
  • the system 1 retrieves the recurring patient file from the disk 18 ( Figure 1).
  • the recurring patient file will contain the additional information (e.g. physician name, telephone number and client number) which is required to produce an order entry for testing the specimen.
  • the system 1 will store the patient files for a selected time, e.g. for a period of 13 months. If the patient does not make a return visit within the 13 month period, then the patient is not a recurring patient so the system 1 will delete the recurring patient file from the disk 18 ( Figure 1). This is done to keep the system 1 (and disk 18) clear of inactive patient files.
  • step 212 is undertaken which involves entering the requested tests.
  • step 212 involves using the bar-code scanner 26 to read or scan the bar-codes corresponding to the tests requisitioned by the physician.
  • the bar-code for the requisitioned test(s) is scanned from the test code template 34 ( Figure 1).
  • the test code template 34 will contain a list of the tests (and their corresponding bar-codes) which are administered at the particular testing facility. For example in the province of Ontario, the test code template 34 can consist of the bar-codes for tests which are covered under the Ontario Health Insurance Plan.
  • the laboratory technician simply runs the bar-code scanner 26 across the appropriate bar ⁇ code on the test code template 34. Any additional tests can be entered manually using the keyboard 22.
  • the remaining steps involve the system 1 generating the labels 36 based on the information in the requisition form, the patient file and the scanned test requests.
  • the function of these labels is to provide a means for identifying the specimen(s) from the time they are taken from the patient to the time the specimen reaches the testing bench.
  • the system 1 For the purpose of identifying the specimen, the system 1 generates an accession number.
  • the accession number is a number which is assigned to a patient specimen on a per requisition form basis. From the collection stage through to the point of testing (and post-test reporting), the accession number provides a unique code for identifying a patient's specimens in the system 1.
  • the accession number is a nine digit code comprising a base accession number and a two digit suffix (which can be used to identify special types of tests). All of the specimens taken from a patient at a specimen collection session as a result of a given requisition form will have the same accession number, but the suffix attached to the accession number may vary.
  • the system 1 produces a number of labels 36 which include the accession number and other information in machine-readable and human readable form. The system 1 can generate the following labels:
  • the above labels can be divided into two general categories based on their function.
  • the Requisition, Test List and Form labels fall into one category and are used primarily for collecting and tracking the specimens (and the corresponding test results).
  • the function of the other category comprising the Test and Collection labels is to provide "test specific" labels.
  • the Test and Collection labels are test specific because they include information in both human-readable and machine-readable form which specifically pertains to the testing to be done on the labelled specimen.
  • the system 1 can be integrated with automatic /machine sorting equipment to provide highly reliable specimen identification and tracking. In practical terms, this means reduced labour and operating expenses, with an increased through-put of specimens. In addition, minimized human handling lowers the bio-hazard and the risks due to human error.
  • FIG. 3 shows a REQUISITION label 300, a TEST LIST label 302, and a FORM label 304.
  • Each label includes a number of data or information fields.
  • like fields on the labels are designated by the same reference.

  • the Requisition label can also include one or more carbon copy or "cc:" fields 324.
  • the carbon copy field(s) 324 lists persons, in addition to the requesting doctor listed in field 320, who should receive a report of the patient's test results.
  • the Requisition label is usually attached to the Requisition form so that the bar-coded accession number can be easily machine scanned to track or sort the corresponding specimen prior to testing and to report the results after testing.
  • the Test List label 302 does not contain any machine-readable bar-coded information, e.g. the bar-coded accession number field 308.
  • the function of the Test List label 302 is to list the tests which were requested for the patient.
  • the information fields on the Test List label 302 are all in human-readable form and comprise: the accession number field 306, a test count field 326 (listing the number of tests to be conducted), a test label count field 328 and a test listing field 330 (which lists the tests by name). In the present embodiment, a total of 16 tests can be printed on a Test List label 302.
  • Test List label 302 is generated by the system 1.
  • the number of Test List labels 302 (i.e. one or two) for a requisition is indicated by the test label count field 328 (e.g. 1 of 1 or 1 of 2).

  • the primary function of the secondary bar-coded field 416 shown in Figure 4 is to provide a machine-readable representation of the testing destination (i.e. work-bench) for the specimen. If the specimen is destined for batch testing, the bar-coded field 416 will be the machine- readable representation of the work-bench for the particular test as shown for Test labels 402,404 and 406. As shown in Figure 4, there is a human- readable test area field 426 which appears above the secondary bar-code 416. The test area field 426 indicates in human-readable form the work ⁇ sheet. If, on the other hand, the specimen is to be individually tested, the bar-code 416 still appears as a machine-readable code corresponding to the work-sheet which, in turn, indicates the work-bench.

  • (work-sheet) bar-code 416 is printed according to the industry standard I- 2/5 format.
  • the system 1 will generate the labels (shown as 36 in Figure 1) in step 214.
  • the labels can be routed either to the network printer 12 or to a local printer 28, as shown in Figure 2. In most cases, the laboratory technician will choose the local printer 28, if available, in order to expedite processing. In the preferred embodiment, the labels are 2.5 x 1.375 inches.
  • the laboratory technician prepares the specimen containers according to the tests which will be conducted. This step involves attaching the test labels to the specimen containers. As will be explained with reference to Figure 8, the system 1 will itself determine the number of containers and test labels that are required for a particular test. Once the containers have been prepared, the specimens are collected from the patient. For hematology tests, for example, blood is drawn from the patient.
  • the specimen is a collection sample (i.e. the test label does not include three asterisks "***") as determined in step 218, then the specimen must be aliquotted or divided into smaller units for testing.
  • the specimen is aliquotted and the test labels 400 are attached to the aliquotted specimens at step 220.

  • a feature of the present invention is the generation of machine-readable codes on the Test labels 400.
  • the machine-readable codes allow the specimens to be routed and batched using automatic sorting machines such as the 1000 Sorter Module which is manufactured by AutoMed in Arden Hills, Minnesota.
  • the automatic sorting machines read the bar- coded test information and group the specimens according to the test to be performed by work-sheet.
  • the sorting machine can group specimens, which as shown in step 224, are destined to a work-bench which has a specific instrument, such as the known Kodak tester.

If the requisition labels 300 have not been printed, then program control passes to blocks 510,512 and 514/516 as discussed above. Otherwise, program flow is directed to block 520 which includes the logic for generating the test labels 400. In block 520, the label program 500 generates a data structure which is used in block 522 for printing the Test labels 400. As will be discussed in detail below with reference to Figure 8, the label program 500 includes logic for determining the number of Test labels 400 which will be needed for a particular test.
  • program flow is directed to blocks 524 to 526 which process the print request according to the printer selection which was made by the laboratory technician at the order entry stage. If the network printer 14 was selected,then the print job is routed to a network printer 14 in block 526. If a local printer 28 was selected, the labels 400 are printed on the slaved printer 28 in block 528. The laboratory technician next prepares the specimen containers by attaching the respective test labels as per step 216 in Figure 2.

  • the initialization routine 600 first creates a local array for storing the transaction record at step 602.
  • the routine 600 sets up the definitions for the printers, i.e. network printer 14 or local printer 28.
  • the routine 600 creates two tables or arrays, Hl() and H2(), for hematology tests.
  • the initialization routine creates a look- up table for the test codes and suffixes associated with the KODAK (trade mark) tester.
  • the routine creates a look-up table for the codes associated with glucose testing.
  • the routine defines a look-up table for the test codes associated with carbon dioxide testing, and a look ⁇ up table for the hepatitis test codes at step 614.
  • the initialization routine creates an array to define the tube types and their respective usable volumes. It will be appreciated that the above look-up tables and arrays depend on the type of tests which can be performed, and therefore other tests would require different look-up arrays or tables.
  • Figure 7 shows in greater detail the logic steps for de-piecing the transaction record in block 508 of Figure 5.
  • the function of the program 500 in block 508 is to determine the tests that have been requested on a requisition form (i.e. order entry) and assigned an accession number. This involves de-piecing the transaction record which is passed to the label generation program 500 when it is called.
  • the first step in de-piecing the transaction record involves building a local array, xx(), based on the test code(s) for the accession number (i.e. requisition form).
  • the test codes are the electronic representation of the test requests which were scanned in step 212 ( Figure 2). It will be recalled that the accession number is assigned to a requisition form and this accession number is then used to identify the tests which have been requested by the physician for that order entry.
  • the local array xx() is used to store the test codes and data which will be used to generate the test labels for the accession number.
  • program flow proceeds to printing the requisition label 300, test list label 302 and form label 304 (if necessary).
  • the program 500 determines what type of printer (i.e. network printer 14 or local printer 28) was selected.
  • the requisition label 300 is printed.
  • the program 500 then proceeds to block 515 which involves printing the test list label 302 on the selected printer. Since form labels are only required for selected tests, program flow is next directed to decision block 517 which determines whether form labels 304 are needed. If form labels 304 are needed, program flow proceeds to block 519 which prints the form labels 304, otherwise, the printing operation of block 519 is bypassed, and the program flow proceeds to step 520 ( Figure 5).
  • FIG. 8(a) and 8(b) show in detail the logic steps comprising the program block 520 in Figure 5.
  • the program 500 creates a local data file or structure (not shown) which is then used to generate a printer control data file which is sent to the selected printer, network 14 or local 28.
  • the control data file provides the format and control codes for the printer to print the required labels, e.g. the requisition label 300, the test list label 302 and the test label(s) 400.
  • the label generation program 500 uses the local array xx() to create the local data file or structure.
  • the first operation in block 700 involves reading in the patient demographic data. It will be recalled that the patient demographic data is included in the patient file which is stored on disk 18. The patient demographic data is passed to the program 500 as data which is stored in computer memory.
  • the program 500 uses the patient demographic data to generate the patient name field 310, the patient sex field 311, the date of birth field 312, the health card number and billing type fields 314,316, the patient telephone number field 318, the client (doctor) name and client number fields 320,322, and carbon copy field 324. These fields appear on the Requisition, Test List and Form labels 300,302,304 as was discussed above for Figure 3.
  • program flow moves to decision block 702.
  • decision block 702 the program 500 checks the requisition done software flag to determine if the Requisition label 300 and Test List labels 302 (and Form label, if needed) have been printed. It will be understood that label generation program 500 can be called after the Requisition labels 300 have already been printed. If the Requisition labels 300 have not been printed, then program flow is directed to block 704. In block 704, the program 500 prints the Requisition, Test List and Form labels 300,302,304 by creating a printer control file which is sent to the selected printer 14 or 28.
  • the program 500 creates the printer control file from the retrieved patient demographic data and the accession number assigned to the patient's requisition.
  • the printer control file is an electronic representation of the label in a format which is recognizable by the selected printer 14 or 28.
  • the printer control file will include special control codes for generating the accession number bar ⁇ code field 308 (format Code 39) and the secondary bar-code field 416 (format 1-2/5). The form of these codes will be dictated by the communication/ control protocol for the printer (e.g. Fargo Prodigy printer).
  • the remaining steps in block 520 involve generating the test specific information which is printed on the Test and Collection labels 400.
  • the program 500 generates the test specific information based on the test codes which were scanned in step 212 of Figure 2 and any special exception testing.
  • the test specific information is then combined with the patient demographic data to produce a printer control/ data file which is sent to the selected printer 14 or 28.
  • the program 500 includes logic to determine how may labels are needed for each type of test.
  • the first step in generating the test specific information involves examining each test code.
  • the program 500 checks the test code(s) for the accession number which are stored in the local array xx().
  • the test codes are examined to determine if the test label(s) 300 should be printed for the accession number.
  • the test code may indicate a delayed test, and therefore it is unnecessary to print the Test label until specimen is taken from the patient.
  • the program 500 suppresses printing a Test label 300 by removing the test code from the local array xx().
  • the program 500 proceeds to a decision block 708.
  • the program 500 determines if the test is a replicate test.
  • a replicate is a test which can be ordered more than once for a specimen. Therefore, to identify the replicate specimen/test the program 500 appends a suffix to the accession number for each replicate test.
  • the program 500 uses this logic block to determine the number of replicates and therefore, the number of Test labels 400 that will be needed.
  • the program generates a suffix which is appended to the accession number field 308 on the Test label 400.
  • test flow is directed to another decision block 710 which checks a replicate suffix flag.
  • the suffix flag is set when the appropriate number of replicate test labels have been calculated (not shown). If the suffix flag is not set (i.e. additional test labels are required for the replicates), the program 500 moves to block 712. In block 712, the program increments a suffix counter and generates a replicate suffix which is appended to the accession number. The suffix count is indicative of the replicate count. The accession number with the appended replicate number is then stored in the local array xx(). The steps in blocks 708 through 712 are repeated until the appropriate number of replicate accession numbers (which correspond to Test labels 400) are produced.
  • each accession number entry in the local array xx() will correspond to a Test label 400.
  • each Test label 400 will appear in the data file as a series of entries having the same accession number, but with different replicate suffixes. If the suffix flag has been set (block 710) or the test request is not a replicate test (block 708), then program 500 moves directly to block 714. In block 714, the program 500 assigns the accession number to the test code.
  • the program 500 then moves to block 716.
  • the program 500 determines the testing laboratory location assigned to the accession number. This logic step is included because the location at which the specimen is taken may not be the location of testing, for example, the specimen is a collection specimen which will be aliquotted (divided) at another location. Therefore, it is not necessary to print Test labels at the time of taking the specimen.
  • the program 500 commences a sequence of steps to process tests having unique characteristics.
  • the program 500 provides exception processing for hematology tests and Kodak (trade mark) type tests. It will be appreciated by those skilled in the art that the exception processing is dependent on the specific test types and can be modified for different types of tests.
  • the program 500 processes the hematology type test codes starting at block 718.
  • the purpose of the hematology test processing is to produce a hematology mnemonic (i.e. field 408 on the Test label 400) which is a combination of all the requested hematology test codes.
  • the program 500 produces a single Test label 400 per accession number.
  • the hematology test codes are categorized either as regular hematology tests or as special hematology tests.
  • the regular hematology test codes include the known hematology tests: hemoglobin, hematocrit, white blood cell count and red cell blood count; and the special hematology test codes include the known hematology tests: platelet count, sed rate (wintrobe), sed rate westergren non citr, sed rate westergren-citr, red cell indices, reticulocyte count, eosinophil count, and blood film examination.
  • the first step in the hematology processing involves examining each of the hematology test code(s) in the local array xx() for the accession number.
  • the program flow moves to test 720 to determine if the test code belongs to the regular hematology category. If the test code is a regular hematology test code, the program 500 adds the test code to the local array Hl(). If the test code is not a regular hematology test, the program 500 moves directly to block 724 to determine if the test code is a special hematology test code. If the test code belongs to the special hematology category, the program 500 adds stores the other local array H2(). The program 500 will pass through the hematology test blocks 720 and 724 until all the test codes are checked for the accession number.
  • the program 500 will generate a Test label 400 for each Kodak test code.
  • the program 500 appends the Kodak specimen identifier to the accession number in block 730. This step produces a new accession number code which results in a Test label 400. If the test code is not a Kodak test, the program 500 bypasses block 730. The program 500 passes through the hematology and
  • the program 500 then moves to block 736 to determine the number of Test labels 400 to be printed.
  • the program logic in block 736 is based on the premise that one Test label 400 is printed per test code, unless the test type requires more than one label, e.g. replicate tests or Kodak (trade mark) tests. If more than one Test label 400 is required for a particular test, the number of labels needed can be stored as part of the accession number/test code entry in the local array. (The system 1 will also produce multiple Test labels 400 for a collection specimen at the aliquot stage.) Since only the Test labels are generated on an as needed basis, the laboratory technician can use the number of Test labels 400 as a guide for determining the number of specimens to be collected from the patient.
  • the program 500 generates the printer control data files which comprise the test information, the patient demographic data, and the printer control codes which define the appearance of the Test labels 400.
  • the program 500 downloads the printer control data files to the selected printer 14 or 28 and the printer 14,28 prints the labels on a self-adhesive strip for example.
  • Test (and Collection) labels have been printed as discussed above, the process turns to collecting and testing the specimens.
  • the system 1 according to the present invention can also be used for sorting and tracking the specimens from the collection stage to the point of testing.
  • Figures 9(a) and 9(b) show in flow chart form a method 800 according to the present invention for sorting and tracking the specimens from collection to testing in the laboratory facility.
  • the method 800 shown in Figure 9 is designed to provide special handling for high priority specimens which are to be shipped to remote or different testing facilities.
  • test and collection labels 400,406 Figure 4
  • the laboratory technician attaches the labels to the appropriate specimen containers (step 802).
  • This task is facilitated by the tube and minimum volume fields 418,420 ( Figure 4) which indicate the type and size of specimen container to be used, for example, collection or test tube and minimum volume of 5.0 millilitres.
  • the collection containers are usually different from ordinary testing containers, e.g. collection containers may have a pierceable and self- resealable top which facilitates removing a portion of the contents into aliquot containers.
  • the next step (804) involves obtaining the actual specimens from the patient and this will depend on the type of test and/or specimen. In hematology tests, for example, a quantity of blood is drawn from the patient. After the specimen(s) has been collected, the specimen container is sealed. This completes the collection stage and the processing of the specimens turns to the delivery of the specimens to the appropriate testing facility (and work bench) for testing, as will be discussed with reference to steps 806 to 824 in Figure 9(a).
  • the labels of the specimens are scanned to check for high priority or special status specimens (as indicated by the processing priority field 414 shown in Figure 4). If the specimen has a special status (step 810), then the specimen is packed in a special shipping bin, which includes its own bar-code identifier. Typically, special status specimens are shipped on an expedited basis and a waybill is generated to track the shipment of the specimen.
  • the waybill is generated in step 810 by scanning the accession and work-sheet bar codes on the test or collection 400,406 labels attached to the specimen containers.
  • the waybill is completed by providing a waybill time and scanning the bar-code on the shipping bin in step 812.
  • the waybill is transmitted electronically to the testing facility ahead of the specimens which are shipped on an expedited basis in step 816. Once the specimens arrive at the testing facility they can be checked against the waybill (see below).
  • Step 818 can include scanning the bar- coded labels to produce a waybill or shipping list, and the shipping container can have its own bar-code which is scanned on the waybill (just as for special status specimens discussed above), so that regular or non ⁇ urgent specimens can be tracked in the same manner.

Abstract

L'invention concerne un système de production d'une pluralité d'étiquettes destinées à être utilisées dans l'identification et la recherche de spécimens à analyser en laboratoire et à être utilisées avec la carte (30) d'un patient dans laquelle sont codées des données relatives au patient. Le système est constitué d'un lecteur (24) de cartes conçu pour lire des données relatives à un patient mémorisées sur une carte (30) de patient, d'un lecteur (26) de codes à barres pour la lecture des codes des analyses à partir d'un modèle (34), et d'un ordinateur (10) pour la production d'étiquettes (36) à partir des données relatives au patient et des codes d'analyse lus. Les étiquettes (36) sont imprimées sur des bandes adhésives et comportent les étiquettes de demande, de liste d'analyses, de formulaire et d'analyse. Lesdites étiquettes de demande, de liste d'analyses, et de formulaire sont utilisées pour la recherche de formulaires papier associés à l'analyse du spécimen en question. De plus, l'étiquette d'analyse est attachée directement à un tube contenant le spécimen, et sert à la recherche et au tri du spécimen, depuis le point de collecte jusqu'au banc d'essai. L'étiquette d'analyse présente un certain nombre de champs de support d'information dont un code lisible par une machine constituant un code d'identification unique pour la recherche et le tri du spécimen. L'étiquette d'analyse contient également un deuxième code lisible par une machine indiquant l'analyse à effectuer sur le spécimen. La structure du code lisible par une machine permet le tri automatisé des spécimens. Lesdits codes lisibles par une machine peuvent également être utilisés conjointement avec un code binaire d'expédition lisible par une machine de manière à produire un bordereau d'expédition (et de réception) des spécimens vers un laboratoire éloigné. Ledit système présente également la capacité de déterminer le nombre d'étiquettes d'analyse nécessaires pour un spécimen particulier, ce qui évite l'impression inutile d'étiquettes.
