1. A method of making a strip for testing for the presence or concentration of an analyte in a fluid comprising:providing a support member with a capillary tube positioned on one side of the support member and communicating with the opposite side of the support member through an aperture in the support member;mounting a spreading layer on the opposite side of the support member and in communication with the aperture in the support member; andmounting a reagent layer on the spreading layer. 2. A method of claim 1 comprising:mounting a carrier strip on the reagent layer opposite the spreading layer; andproviding an aperture in the carrier layer for observing or measuring the indication of the reagent. 3. A method of claim 1 comprising:preassembling the carrier layer, the reagent layer and the spreading layer; andmounting the preassembled layer on the support member. 4. A method of claim 1 comprising:providing a support member with a recessed area for receiving the spreading layer and the reagent layer. 5. A method of claim 2 comprising:providing a support member with a recessed area for receiving the spreading layer and the reagent layer. 6. A method of claim 3 comprising:providing a support member with a recessed area for receiving the spreading layer and the reagent layer. 7. A method of making a strip for testing for the presence or concentration of an analyte in a fluid comprising:providing a support member with a capillary;mounting a spreading layer onto the support member in communication with the capillary; andmounting a reagent layer on the spreading layer. 8. The method of claim 7, wherein the capillary defines a predetermined volume. 9. The method of claim 1, further comprising:providing the support member with barrier members; andcreating a predetermined volumetric space by deforming the spreading layer into a shape conforming to the barrier members. 10. A method of claim 7 comprising:mounting a carrier strip on the reagent layer opposite the spreading layer; andproviding an aperture in the carrier layer for observing or measuring the indication of the reagent. 11. A method of claim 10 comprising:providing a support member with a recessed area for receiving the spreading layer and the reagent layer. 12. The method of claim 7, further comprising:providing the support member with barrier members; andcreating a predetermined volumetric space by deforming the spreading layer into a shape conforming to the barrier members.
