Abstract

Conventional laboratory tests require calibration before each test. This results in the need for a reagent for calibration before each test. Additionally, calibration takes a long time, and the total TAT (Turn Around Time) of a testing system increases. The testing system thus suffers from the difficulty of improving the testing efficiency. This invention, which has been made to solve the problem, provides a testing element for performing a laboratory test, wherein the testing element includes an information recording section at the surface of and/or inside the testing element, and the information recording section stores information on a characteristic of the testing element.

Claims

1. A testing element for performing a specimen test, comprising:

an information recording section installed at a surface of and/or inside the testing element;

a plurality of fluid paths; and

a plurality of heater electrodes for heating each interior of the fluid paths, wherein information on a characteristic of the testing element is stored in the information recording section, the information including, as pieces of information, characteristics of the respective fluid paths which include a pressure resistance or a value of heater electrode resistance, and

wherein the information on the characteristic is read-out to set a control parameter for performing the specimen test.

2. The testing element according to claim 1, wherein the information recording section is a one-dimensional and/or two-dimensional bar code.

3. The testing element according to claim 1, wherein the information recording section is a semiconductor chip which reads out information through wireless communication.

4. A testing apparatus for performing a specimen test, comprising:

The testing element according to claim 1;

a unit configured to read out information on the characteristic of the testing element stored in the information recording section installed at the surface of and/or inside the testing element;

a unit configured to set a control parameter of the testing element based on the read-out characteristic of the testing element; and

a unit configured to use the testing element by using the read-out control parameter of the testing element to perform the specimen test.

5. The testing apparatus according to claim 4, wherein each time the apparatus performs a specimen test, the apparatus saves a serial number specific to a testing element used, a control parameter used for the testing element, and an installation environment of the apparatus when the test is performed, together with a result of the test.

6. The testing apparatus according to claim 5, further comprising a unit configured to update a database of a testing system with a control parameter, based on a result of a test by a testing element passed from the testing apparatus, the serial number specific to the testing element used at the test, the control parameter used for the testing element, and the installation environment of the apparatus when the test is performed.

7. A testing system for performing a specimen test, comprising:

the testing apparatus according to claim 4;

a unit configured to access a database connected to the system over a network; and

a unit configured to download, from the database, a latest table set for referring to a control parameter used when a testing element used by the testing apparatus is used, based on a serial number specific to the testing element, and configured to pass a result to the testing apparatus.

8. The testing element according to claim 1, wherein the characteristics of the respective fluid paths are information obtained by measuring in advance how much a value obtained by the testing element deviates from a reference value.

9. The testing element according to claim 1, wherein the test element is an element for DNA analysis using PCR.
