Embodiment Construction
[0013] The present invention provides a test strip for determining the concentration of at least one analyte in a physiological sample and methods of making and using such a test strip. This test strip has multiple reaction zones bounded by a hydrophobic barrier. The reagent composition in each reaction zone may be the same or different. Alternatively, each reaction zone may have a separate liquid channel, or the separate channels of two or more reaction zones may be combined into a single channel. When in use, a sample is applied on the test piece, a signal can be detected and the content of the analyte in the sample can be correlated with this signal. The present invention also provides methods of applying a hydrophobic barrier using thermal transfer techniques to make such test strips. Finally, the invention provides kits for carrying out the method.
[0014] While the present invention has been described, it is to be understood that the invention is not limited to the p...
