Abstract:

A test slide (10) for performing diagnostic tests for detecting the presence of cells, their enzymes, metabolites and other cellular derivatives. The test slide (10) comprises a support strip (14), a coating (34) comprising a carrier and a diagnostic reagent disposed on the support strip (14), and a mount (12) comprising a front wall (18) and a rear wall (20). The coating (34) has the properties of being dry and stable, and water soluble. Further, the coating (34) and the diagnostic reagent are capable of rehydration. The support strip (14) is disposed between the front wall (18) and the rear wall (20) of the mount (12). Both the front (18) and rear (20) walls can have coinciding openings (28,28a) that overlie the support strip (14) thereby allowing spectroscopic, visual and microscopic examination of the support strip (14).
