Non-visible detectable marking for medical diagnostics

摘要

Sample media for the analysis of analytes in a fluid test sample includes a carrier, at least one test field on the surface of the carrier including at least one reagent reactive with the analytes and capable of providing a detectable response. A non-visible bar code formed by at least two distinct non-visible marker fields is located on the carrier. The marker fields are configured to reflect electro-magnetic (EM) radiation within one or more ranges of non-visible wavelengths to form a coded sequence of reflectances correlated to identification of the sample media.

1. Sample media for the analysis of one or more analytes in a fluid test sample which comprises:
a carrier; a first test field and a second test field, the first test field and the second test field being disposed on the surface of the carrier including at least one reagent reactive with the one or more analytes and capable of providing a detectable response, the first test field being the closest test field to a distal end of the carrier; a non-visible bar code formed by at least two distinct non-visible marker fields disposed on the carrier, the non-visible marker fields are visibly transparent on the carrier and are configured to reflect electro-magnetic (EM) radiation within one or more ranges of non-visible wavelengths to form a coded sequence of reflectances which sequence correlates to information concerning identification of the sample media, the non-visible bar code being (1) separate from the first test field and the second test field and (2) disposed in between the first test field and the first distal end of the carrier; and a visible bar code formed by at least two distinct visible marker fields disposed on the carrier, the visible marker fields being configured to reflect EM radiation at ranges of wavelengths in the visible light spectrum and predetermined to form a coded sequence of reflectances which sequence correlates to other information concerning identification of the sample media, the visible bar code being (1) separate from the first test field and the second test field and (2) disposed in between the first test field and the first distal end of the carrier.
