Abstract

A urine test sheet which can reduce the workload of a person performing a test through the use of a urine test sheet, caused by the above-mentioned temporary restriction and which makes it possible to obtain a determination result having high reliability. The urine test sheet includes a support, and a reaction reagent which is formed on the support, and by the urine test sheet being immersed in urine to be a specimen and then being taken out, shows a reaction for a prescribed subject to be tested after a prescribed period of time, wherein a detection member in a pad-like shape including the reaction reagent and a reaction-terminating agent having an action causing the reaction to terminate is formed on the support, the reaction-terminating agent is covered with a water-soluble material, and the water-soluble material causes the reaction-terminating agent to act by being dissolved by moisture in the urine.

Claims

1. A urine test sheet comprising:

a support, and

a reaction reagent which is formed on the support, and by the urine test sheet being immersed in urine to be a specimen and then being taken out, shows a reaction for a prescribed subject to be tested after a prescribed period of time,

wherein

a detection member in a pad-like shape including the reaction reagent and a reaction-terminating agent having an action causing the reaction to terminate is formed on the support, the reaction-terminating agent is covered with a water-soluble material, and the water-soluble material causes the reaction-terminating agent to act by being dissolved by moisture in the urine.

2. The urine test sheet according to claim 1, wherein

the amount of the water-soluble material is set so as to cause the reaction-terminating agent to act and to terminate a reaction of the reaction reagent after each of the prescribed periods of time specified for each of the subjects to be tested.

3. The urine test sheet according to claim 1, wherein

the detection member is formed by arranging, in a layered form, the reaction reagent and the reaction-terminating agent covered with the water-soluble material.

4. The urine test sheet according to claim 1, wherein

the detection member is formed by covering the whole outer surface of the reaction-terminating agent with the water-soluble material to thereby be formed into a granular shape, and by containing, in a plural number, the reaction-terminating agent in the granular shape in the reaction reagent.

5. The urine test sheet according claim 1, wherein

detection members corresponding to two or more subjects to be tested which are different in the prescribed period of time are formed on the support, and around each of detection members, an encircling part that blocks an action of the reaction-terminating agent contained in an adjacent detection member is provided.

6. The urine test sheet according to claim 5, wherein

an outer surface of the encircling part includes a material that neutralizes a reaction of the reaction-terminating agent.

7. The urine test sheet according to claim 1, wherein

change in coloring of the detection member caused by a reaction of the reaction reagent for the prescribed subject to be tested is set in a stepwise manner by shading, detection members corresponding to the number of the set steps are formed on the support, marks showing each of the steps colored in the same color as coloring of each of the set steps are indicated on the support so as to be readable from on each of the detection members, and marks colored in the same color as coloring of a detection member which has changed by the reaction, and colored in color paler than the color are unreadable from on the detection member.

8. The urine test sheet according to claim 1, wherein

change in coloring caused by a reaction of the reaction reagent for the prescribed subject to be tested is set in a stepwise manner by shading, detection members corresponding to the number of the set steps are formed on the support, a mask having window portions capable of observing each of the detection members is provided via a film colored in the same color as coloring of each of the set steps, a mark indicating each of the steps corresponding to each of the window portions is described on the mask, and when the mask is overlapped upon the support after the reaction, as to coloring observed via the window portion, from window portions having the same coloring as the support after the reaction and having paler color than the coloring, the coloring can be observed.

9. The urine test sheet according to claim 8, wherein

the detection member includes a mark that is formed of the reaction reagent and indicates each of the steps, and when the mask having the window portion is overlapped upon the support after the reaction, the mark is unreadable from window portions having films colored in the same color as coloring of the mark after the reaction and colored in color deeper than the color.

10. The urine test sheet according to claim 9, wherein

the support is provided with a window portion having a film allowing each of the marks to be read, the window portion being provided on the face opposite to the detection member-formed face.

11. The urine test sheet according to claim 7, wherein

at least one of information identifying a subject, information specifying a subject to be tested, and information showing determination result corresponding to each of the marks is indicated on the support by an optically readable code.

12. The urine test sheet according to claim 7, wherein

each of the detection members for every plural and different subject to be tested is arranged in parallel on the support.
