1. A test strip card for testing a property of a fluid specimen, said test strip card comprising:
- a comparison scale that comprises a continuous scale of visual levels;
a test strip having (a) a reaction zone which is part of a reagent pad and (b) a zone that is not part of the reaction zone, the test strip being movably coupled to said test strip card for performing a reaction on the reaction zone on the reagent pad of the test strip;
a window along said comparison scale for viewing (a) the reaction zone of the test strip and (b) at least a portion of the zone of the test strip that is not part of the reaction zone, wherein said test strip is movable with respect to said comparison scale to align said reaction zone with a matching visual level on said comparison scale whereby indicating the property of the specimen;
wherein said test strip card further comprises a front wall, a back wall, and a pocket between said front wall and said back wall; and
said test strip is movably located within said pocket in said test strip card;
wherein said window is formed in said front wall along said comparison scale; and
part of said reaction zone on said test strip is visible through said window along said comparison scale;
wherein the test strip card further comprises transparent material in said window through which said reaction zone is visible.

3. A method of testing a property of a fluid specimen, said method comprising:
-
applying a fluid specimen to a test strip movably coupled to a test scale card bearing a comparison scale, wherein the test strip includes a reaction zone that is altered upon contact with the fluid sample; and
moving the test strip with respect to the comparison scale to align the reaction zone with a matching region in the comparison scale indicating information about the fluid specimen characteristic being tested;wherein the test strip remains coupled to the test scale card during applying of the fluid specimen, wherein said test scale card further comprises a front wall, a back wall, and a pocket between said front wall and said back wall; and
said test strip is movably located within said pocket in said test scale card. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12)
