Abstract

It is an object to provide a test instrument and an optical measurement apparatus which enable easy matching of test results when tests by optical measurement are performed with respect to a large number of patients.

To the above end, a test instrument B is provided, which includes reagent retaining portions 8A, 8B, 8C retaining a reagent which reacts with a sample to produce a color reaction. The test instrument B includes a patient information entry section 64 as an example of patient identifying information region in which patient identifying information is to be written.

Claims

1. An optical measurement apparatus to which at least one test instrument is set, the test instrument comprising:

at least one reagent retaining portion retaining a reagent which reacts with a sample to produce a color reaction; and

a patient identifying information region for entering patient identifying information;

the optical measurement apparatus comprising;

a reader for reading color development of the at least one reagent retaining portion;

a controller for performing test processing; and

an output unit;

wherein the reader is configured to read the patient identifying information region,

the controller generates test result output data using image data of the patient identifying information region obtained by the reading operation of the reader, and

the output unit performs output processing based on the test result output data transmitted from the controller, and said output processing includes outputting of an exact copy of images put in the patient identifying information region.

2. The optical measurement apparatus according to claim 1, wherein the output unit comprises a printer that performs printing, based on the test result output data, of a test result including the exact copy of images put in the patient identifying information region.

3. The optical measurement apparatus according to claim 1, wherein the output unit comprises a display that displays, based on the test result output data, a test result including the exact copy of images put in the patient identifying information region.

4. The optical measurement apparatus according to claim 1, further comprising an external connector connected to the controller, wherein the controller is configured to transmit the test result output data through the external connector.

5. The optical measurement apparatus according to claim 1, wherein the optical measurement apparatus is configured to allow setting of a plurality of test instruments including said at least one test instrument.
