- the present invention concerns in one aspect a method for checking one or more parameter(s) of a sample container between the step of filling the sample in the container and the initiation of the transport of said sample container in a sample container rack, wherein said sample container is configured to be placed in a sample container rack designed to receive one or more sample container(s) as a base station.
- the underlying smart analytics concept combines the latest methods of digitiza- tion and innovative medical technology to significantly improve the integrity of human blood and other body fluids, i.e. samples, despite complex supply chains for patients and researchers.
- the methods for checking or monitoring one or more parameter(s) of a sample container according to the invention allow the user to check, inter alia, the loca tion, temperature and quality of samples in real time, and to read the stored information of the sample process directly from the sample or container rack, e.g. via an App, e.g. the smart4app or on the basis of a network based data management system.
- the sample containers and the sample container rack within the context of the methods according to the present invention may communicate directly with existing analyzers, e.g.
- analyz ers of the Cobas platform of Roche or other similar systems thus reducing the handling effort of the samples.
- they may automatically combine the data from the sample course with corresponding analytical data. This ensures that samples which do not meet predefined quality requirements do not enter into the analyzer system, or are re-used by an analyzer. This results in an unprecedented degree of safety, traceability and quality control when using different samples.
- the producer of an ana lyzer can convert its own platform into a smart digital device without great overhead, thus implementing its own digitization strategy.
- the present invention thus aims at providing methodology for the checking and monitoring of sample containers before and during the transport of blood and other medical samples, as well as communication and software solutions for existing plat forms, e.g.
- An example of an already existing analyzing system in the field of automated la boratory diagnostics is the Cobas series provided by Roche.
- the present invention also aims at a further development of existing sample container as smart devices, which com municate independently with, e.g. the Cobas analyzers. Thanks to a Cobas-compatible methodology all necessary steps in the area of sample handling are significantly simpli fied. First, the time- and error-intensive repackaging from previously analog mailboxes in Cobas racks is no longer required. In addition, it is now possible for users, for the first time, to sort and/or treat separate samples, which do not meet the quality requirements already stipulated before dispatch, independently through the Cobas platform. For this purpose, the described methods allow to communicate directly with a receiving station, e.g.
- the Cobas platform and informs about the data collected so far by it. If these data do not correspond to previously determined parameters, e.g. temperature, route, time or qualitative parameters, the corresponding samples are automatically sorted out, or not measured, e.g. by the Cobas device or handled separately. Further options for sub sequent handling of these samples are also envisaged. In this way, the described meth ods allow for an auto-correction for faulty data and the underlying platform technology, e.g. the Cobas platform, provides its users with an unprecedented, unique analytical safety frame. An interaction as described for the Cobas platform is envisaged also for any other suitable analyzing platforms known to the skilled person.
- the present invention thus generates, for example, at least three immediate benefits: 1.
- the Cobas platform or any other similar analyzing platform may become a smart device, which comes into contact with the respective samples and exchanges itself about their quality.
- Platform users get maximum security for the analyses performed on their platform devices. Defective samples are sorted out or handled differently. 3. There are significant cost reductions and time savings for platform users by applying the new methods and approaches.

- the "type of the sample container” may be checked with respect to predeter mined types, e.g. in a color coded manner.
- sample containers may differ with respect to the subsequent analysis planned, the identity orform of the sample, e.g. whether it is a blood, a serum, a plasma, a urine, a feces sample etc., or the amount of sample used, the transport conditions etc.
- the information on the type of sample con tainers may be compared with information on the sample container present at the ana lyser location or in a remote server database.
- the "volume of sample container” is meant to constitute a parameter which is connected to the sample type and also the subsequent analysis planned.

- the "filling volume" of one or more sample container(s) in the rack may be de termined and compared with a predetermined range of filling volumes. The filling vol ume may be made dependent on the intended subsequent analysis of the sample, the number of different analyses planned for a patient, minimal volume requirements for certain analyses etc.
- sample number may be provided, e.g. in the form of a barcode, Q.R code or electronically via RFID. Such information may accordingly be checked.
- the "cap color of the sample container” is a parameter which may be linked to the sample type, e.g. blood, serum, urine etc.

Also an identification of sample containers via their color and shape, in the form of cap- tured images, is envisaged.
- index of the sample relating to hemolysis, icterus or lipaemia means that the color of the sample container content is determined since it can potentially indicate hemolysis, icterus or lipaemia. Accordingly, a potential disease state of a patient and/or a corresponding usage modification of the sample from said patient can be de tected via the color of the sample in the sample container. This color change is also known as serum index or HIL-index.
- hemolysis refers to the rupture of erythrocytes resulting in the release of its intracellular components, e.g. haemoglobin, and flooding the plasma or serum with potassium and other internal com ponents.
- the hemolysis of samples may be detected according to a color change of the serum or plasma sample, e.g. from pink to red, de-pending on the number of cells that have lysed.
- the term "icterus” as used herein means jaundice or hyperbilirubenemia, which are typically associated with the presence of high levels of bilirubin due to in creased bilirubin production or inappropriate extraction, e.g. in diseases such as haemo lytic anemia, liver diseases, biliary tract obstruction, etc. Icteric serum or plasma may be detected via changes in sample color from normal straw color to dark or bright yellow.
- lipaemia refers to the presence of excess lipids or fats due to increased concentration of triglyceride-rich lipoprotein in blood resulting in the cloudy/turbid appearance of serum or plasma.
- the "centrifugal status of the sample container” as used herein relates to the determination of a previous centrifugation step performed with the sample or sample container in case of liquid samples, e.g. blood samples. This can be detected by as- sessing the presence of different phases in the liquid sample or the presence of a pre cipitate in the sample container. For example, the presence of liquid or solid phases may provide information on a previous centrifugation or the form and details of a centrifu gation. Similarly, a ratio of liquid and solid phases may be determined which also allows to determine whether a centrifugation has been performed and in which form and length.
- the "content of order form attached to the sample container rack" may comprise information on the samples, the origin of the samples, the destination of the transport, the planned analyses etc. Such information may be checked according to the claimed methodology, when the sample containers are provided in the sample container rack.

The checking of such parameters may, for example, for performed with a lab-on-a-chip unit (LOC), which is provided on the sample containers or in the sample container rack.
- LOC lab-on-a-chip unit
- LOC label-on-a-chip unit
- LOCs use microfluidics to handle small fluid volumes.
- the LOC component may advantageously be connected to the sample containers, whose content may accordingly be analyzed or par tially analyzed directly in the sample container rack. For example, a small portion of the sample may be separated from the sample container and transferred by microfluidics to a LOC module, where one or more biochemical or diagnostic assay(s) may be performed.
- the LOC module may advantageously be used to determine and characterize clinical chemistry, immunological, or haematological parameters, or to determine or characterize disease indicators such as tumor markers, circulating DNA or RNA, or to determine or characterize biochemical properties of a sample, e.g. clotting time or vis cosity of the sample.

- metabolic indicators may include, but are not limited to Glucose, Lactate and the like.
- further health indicators may include, but are not limited to Troponin-T, GDF-15, Ethanol, Uric Acid and the like.
- the mentioned parameters may preferably be measured with devices or sensors as described herein.
- the checking may, in further embodiments, comprise a registering and storing of correspondingly obtained information, as well as a comparison with pre defined target values or corridors of values.
- any parameter measured or monitored may be compared with a database entry as to a desired or undesired value of said parameter, or a corridor of desired values with corresponding limits.
- an alert is produced and/or a decision as to the fate and future of the sample which is associated with the measured value is started.
- said checking is performed in an automatic manner.
- One op tion is to use contactless communication between the sample container and the sample container rack or to automatize reading, image capture and recognition activities.
- an RFID (radio frequency identification) unit for example, the employment of an RFID (radio frequency identification) unit, a Bluetooth interaction, a barcode reading or image capturing is envisaged.
- the checking may ac cordingly be started automatically once a sample container is placed in a slot, e.g. a spe cifically allocated slot or a arbitrarily selected slot of the sample container rack, or if a sensor as mentioned captures an image due to a newly placed sample container or if a contact becomes possible, e.g. via Bluetooth because the sample container is in the vi cinity of the registration unit.
- the term "automated manner via contactless communication” generally relates to an electronic or computerized element which either actively sends out a signal to a base station, or works passively and may react to a signal generated by a base station. In both scenarios, the signal may be transmitted without direct physical contact be tween the sample container and a base station, e.g. via radio waves.
- the contactless communication may, for example, be based on RFID (radio-frequency identification) technology.
- RFID technology uses electromagnetic or electrostatic coupling in the RF portion of the electromagnetic spectrum to transmit signals. RFIDs may generally be classified as active or passive.
- Active RFID systems typically have 3 components: (a) a reader, transceiver or interrogator, (b) antenna, and (c) a transponder or 1C programmed with information.
- Active RFID tags typically possess a microchip circuit (transponder or integrated circuit (1C)) and an internal power source, e.g., a battery, and when operably connected to an antenna, the active RFID tag transmits a signal from the microchip cir cuit through the power obtained from the internal battery.
- active RFID tags such as transponders and beacons are used.
- a system may use an active transponder.
- the reader sends a signal and when the antenna and tag are operably connected, the tag will send a signal back, e.g. with the relevant information programmed to the transponder.
- an active beacon is used wherein the beacon sends out a signal on a periodic basis and it thus does not rely on the reader's signal.
- passive RFID systems comprise (a) a reader, trans DC or interrogator, (b) antenna, and (c) a tag programmed with information.
- a pas sive RFID tag typically includes a microchip or integrated circuit (1C), and it may contain the antenna as an integral component of the tag or as a separate device.
- the tag typically does not include a power source.
- the antenna can be an internal component of the tag, i.e., the antenna and 1C can be contained in a single device. However, until operably connected in the device, the antenna and 1C may not interact. Alternatively, the antenna and 1C may be provided on separate compo nents.
- passive tags wait for a signal from an RFID reader. The reader thus sends energy to an antenna which converts that energy into an RF wave which is transmitted into the read zone.
- the RFID tags internal antenna is typically powered via RF waves. Accordingly, the tags antenna fuel the 1C with energy which generates a signal back to the RF system. Such process of change in the electromagnetic or RF wave, can advantageously be detected by the reader (e-g- via the antenna), which may in turn interpret the information. Accordingly, passive RFID tags have typically no internal power source and normally comprise an 1C and an internal antenna.
- the tag may, in specific embodiments, comprise an electronic product code (EPC) or a similar code, which is 96 -bit string of data. Also envisaged are alternative codes, which allow to identify a product or element.
- EPC electronic product code
- each sample container comprises a passive RFID tag which operates at a unique frequency so that each sample container is distinguishable from the other sample containers. If there is more than one sample container in contact with a base station, i.e. the sample container rack, the frequencies may be read sequentially or simultaneously. To avoid collision between individual tags, collision detection may be used. To this end typically two different types of protocols are used to singulate a par ticular tag, allowing its data to be read in the midst of many similar tags. For example, in a slotted Aloha system, a reader may broadcast an initialization command and a pa rameter that the tags individually use to pseudo-randomly delay their responses. Alter- natively, an adaptive binary tree protocol may be used, wherein the reader sends an initialization symbol and then transmits one bit of ID data at a time. In this scenario only tags with matching bits respond, and eventually only one tag matches the complete ID string.
- the RFID tags may be used at different frequencies, e.g. at a low frequency (LF) of 125-134 kHz, at a high frequency (HF) of 5-7 MHz, at a HF frequency of 13.56 MHz, at an ultra-high frequency (UHF) of 433 MHz, 865-868 MHz, 902-928 MHz, or in the Giga Hertz band of 2.45 to 5.8 GHz.

In the alter native, the sample container may be placed in a specific, predetermined slot within the sample container rack, preferably a master check-in slot as defined herein.

For example, if a sample container is placed in an arbitrary slot, said slot may be assigned for said sample container. Furthermore the availability of said slot for the placement of other sample containers may be denied to avoid mix-ups. In case a placing is performed in an empty slot which is not identical to the predetermined slot, such an activity may lead to the recognition of the occupied slot and a corresponding assignment of the sample container. Alternatively, the operator may be alerted and informed to relocate the sample container.

- Said conversion may be performed by electrical transducers which are capable of converting physical quantities into electrical quantities.
- a ther mocouple may be used that changes temperature differences into a small voltage.
- the term "history log” as used herein relates to the measurement and optional storage of temperature values during a specific period of time, e.g. during the transport of a sample container rack as defined herein, or from inserting a sample container in the rack until the delivery of the sample container to an analyzer or analyzer system as defined herein, or any sub-portion of said period of time.
- the measurements may be performed in a continuous manner, or may be performed periodically, e.g.
- the history log may accordingly be recorded in any suitable place or device, e.g. within a sample container rack, or at a remote receiving station as defined herein.
- the history log may further be available on potentially connected devices such as handheld devices or smartphones, LIS or sample analyzer technology units etc. Also envisaged is the presentation on dashboards as described herein and the opportunity for its printing, exporting or archiving in any electronic format, e.g. text files.
- said temperature parameter history log is used to re- construct the approximate sample collection time point. For example, the decrease or increase of temperature over a defined period of time may be registered and compared with the temperature at the point in time of entering a sample container to the sample container rack. Furthermore, a comparison with environmental temperatures may be performed to allow for a calculation the period of time which has lapsed since a first or initial measurement, e.g. when checking in the sample container, was performed.
- said reconstruction is further based on additional parameter values from the sample container rack such as sample filling volume, sample container type, humidity orfurther parameters. These values may be integrated into the reconstructive calculation of the approximate sample collection time point, e.g. on the basis of the decrease or increase of temperature of the sample in a defined period of time.
- the checked, monitored and/or recorded param eters as defined above, or the temperature parameter history log as defined above is/are transmitted to a remote receiving station as defined above.
- Said transmission of parameter values or logs may be performed once, e.g. a specific point in time such as 10 min, 20 min, 30 min, 60 min, 2 h etc. after the first contact between the sample container and the sample container rack, or 10 min, 20 min, 30 min, 60 min, 2 h etc. after the transport of the sample container rack has started.
- the transmission may be performed several times, e.g. after an adjustable period of time, e.g.
- the transmission is started after one or more specific, e.g. predetermined, geo graphical checkpoint(s) have been reached or passed, e.g. determinable via a GPS func tionality as defined herein.
- the transmission may be started after one or more parameter(s) as described herein above are successfully collected. It is par ticularly preferred that said transmission is automatic.
- othertransmission forms are envisaged, e.g. a semi-automatic version, wherein an operator is asked for permission, or a purely operator-controlled transmission.
- the transmission of parameters is initiated imme diately after the placement of the sample container in the sample container rack, more preferably before the sample container rack's transport is started.
- Transmitted parameters as defined herein above may be recorded in any suita ble manner, preferably in a remote computer sever system as defined herein. It is par- ticularly preferred that the transmitted parameters or parameter values are recorded in a cloud based computer server system.
- transmitted parameter values may additionally be aggregated, e.g. in a specific data format, summarized, e.g. in a specific report format, and/or assessed. The assessment may, for example, include a comparison with reference values, e.g. derivable from a database. These activities are preferably performed in an automatized manner.
- checked or monitored parameter values may be deliv ered to a sample analyzer as defined herein, or to a remote laboratory comprising said sample analyser. It is particularly preferred that the received parameter values are inte grated into the sample analyzer system. Also envisaged is the integration into an LIS or sample analyzer technology unit. In a specific embodiment, said parameter value inte gration is performed via a cloud-based server system automatically, periodically or by request, e.g. after sending the request for a specific barcode of a sample container, or after the sample container has arrived at or was registered by the LIS.
- the received parameters values are provided in the form of a dashboard as defined herein, preferably per each sample container or per sample container rack.
- the information may accordingly be provided on a web page which is linked to a database, or be provided as raw data stream, preferably to an oper ator.
- the fact that parameters have been checked and no deviation from a predetermined value has been detected is transmitted to a remote receiving station as defined herein in the form of a contentless short signal, e.g. an SMS notice.
- the present invention relates to a computer implemented method for checking one or more parameter(s) of a sample container between the step of filling a sample in the container and the analysis of the sample.
- the parameters to be checked comprise or consist of:
- type of sample container preferably identifiable via a color code
- index of the sample relating to hemolysis, icterus or lipaemia
- sample container rack preferably one or more quality parameter(s) of the sample, preferably pH, ionic concentration, and presence of apoptotic, inflammatory or infectious indicators, preferably as defined herein above.
