Information-encoded tests and method
First Claim
1. A test for the analysis of one or more analytes in a fluid test sample, the test comprising:
- a carrier of an absorbent material;
said carrier exhibiting light reflectance within a first predetermined spectral range;
a plurality of test fields on the surface of the carrier;
said test fields including a plurality of test field materials reactive with the one or more analytes and exhibiting light reflectances within a second predetermined spectral range;
said first and second predetermined spectral ranges being distinguishable from one another;
said plurality of test fields being disposed in spaced relation to one another on the carrier, wherein gaps between the test fields exhibit light reflectance within said first predetermined spectral range;
said gaps and said test fields having relative sizes which are optically discernable;
said relative sizes forming a coded sequence that correlates to information relating to the test.

Abstract
A test and method is provided for the analysis of one or more analytes in a fluid test sample. The test includes a carrier of an absorbent material, which exhibits light reflectance within a first spectral range. A plurality of test fields are located on the surface of the carrier, and include test field materials reactive with the analytes and exhibiting light reflectance within a second spectral range. The test fields are located in spaced relation to one another on the carrier, so that gaps between the test fields exhibit light reflectances within the first spectral range. The gaps and test fields have relative sizes which are optically discernable, and which form a coded sequence that correlates to information relating to the test.

22. A test for the analysis of an analyte in urine which comprises:
-
a) an elongated carrier of an absorbent material which allows the analyte and labeled antibodies specific thereto to flow through it along with the urine and to form analyte/labeled antibody conjugates;
b) a plurality of test fields disposed in spaced relation on the surface of the carrier which capture either the labeled antibody or the analyte/labeled antibody conjugate and are capable of providing a first optically detectable response thereto;
c) gaps between said test fields defining a plurality of code fields, the code fields each configured to provide second optically detectable responses which are distinguishable from said first optically detectable responses;
d) each of said code fields and said test fields sized and shaped to have one of at least two discrete dimensional parameters, said dimensional parameters forming a coded sequence corresponding to information relating to the test.
