Description

{METHOD FOR MANAGING MANAGEMENT MATERIALS}

The present invention relates to a method for managing a controlled substance.

A control substance is a substance to be controlled for medical inspection and may include reagents, kits, reference materials, control substances, and the like. Reagents refer to drugs used in the fields of pharmacy, chemistry and medicine to detect or quantify the components of a substance. These reagents can be purchased from a specific manufacturer or manufactured directly in a laboratory or research department. The kit can diagnose blood glucose, hepatitis, and pregnancy by using blood or urine. The kit can be formed in a strip shape with a starting reagent of a material absorbing blood or urine on the top surface of a long and long rod-shaped substrate . In addition, the reference material is a material that establishes a reference point for inspection in the inspection equipment.

Each time this material is received, the user manages and manages the name, the manufacturer, the manufacturing number, the date of manufacture, the quantity of goods, and the like of the substance to be managed by the management substance.

Since the date of receipt and the date of use may be different for such controlled substances, if the manufactured number of the newly received controlled substance is different from that of the previously received controlled substance, or if the manufactured number of the newly received controlled substance is changed Verification of the controlled substance should be carried out.

However, it is difficult to judge whether or not the verification of the corresponding control substance has been performed for each user because there are many kinds of control substances and many users manage or inspect the control substances.

In addition, since the user manages the management substance using different management methods, the verification number of the new control substance is different from the manufacture number of the previously-received control substance or the verification number of the new control substance is changed. There is a problem that it is not performed regularly. Thereby, there is a danger that the control material may be altered to become unusable, or the deteriorated control material may be used to ruin the inspection or to obtain an incorrect inspection result.

Therefore, there is a need for a study of a management method for easily managing a management substance by a user.

The present invention provides a method by which a user can easily manage a management substance.

A management material management method according to an embodiment of the present invention includes: a management information input step of receiving management information on the received management material when a management material is received; Determining whether a verification condition for the received management substance is satisfied based on the input management information; Providing a verification interface that provides an interface for verification of the received management material if the verification performing condition is satisfied; A verification condition information input step of receiving verification condition information for verification of the received management substance; A verification step of verifying the received management substance based on the input verification condition information; And a result storage and output step of storing and outputting a result of verification of the received management substance.

According to the configuration of the present invention, the management method automatically performs notification and verification of the management substance, so that the user can conveniently manage the management substance.

In addition, the management method of the present invention is advantageous in that information can be provided for later comparison and confirmation of results by storing and managing the results of verification.

Such verification condition information can be inputted directly by the user or transmitted through the network from the data storage means or the inspection equipment.

The step of performing the verification of the management substance based on the inputted verification condition information may perform the verification selected by the user based on the input verification condition information.

The step of outputting and storing the results of the verification of the performed control material may store a result of the verification when the verification is completed and may provide a user interface including the result of the verification. For example, when the ferrule validation test for the reagent verification is completed, the difference value between the previously received reagent and the newly received reagent, which is the result of the ferrule validation test, is stored, and a user interface indicating the difference value is provided .

The two samples, Sample1 and Sample2, were diluted in stages and mixed. After judging whether the result was output as a straight line graph, it was confirmed whether the low and high specimens were out of the measurable range and the samples were concentrated or diluted seriously Test results of low or high specimens can be output.

Referring to FIG. 11, the two specimens Sample 1 and Sample 2 are diluted in five steps. Referring to FIG. 12, two specimens Sample 1 and Sample 2 are diluted in ten steps, and the expected values and actual values , The error rate and the recovery rate thereof, and the resultant values (1000, 1010) of the measured values as a linear graph. At this time, actual measured values can be output as one or more, and when two or more measured values are output, the average value of two or more measured values can be output as a final result value or the first measured value can be output as a final result value.

For example, if the measurable range provided by the manufacturer is 3-2000, the minimum value of the measured values for the two samples is 3, and if the maximum value is 2214, the applied AMR may be 3-2214. The user can determine these results according to the error rate or recovery rate.
