Title: Multiple simultaneous testing media

Abstract: A stationary testing media device made of a glass or plastic plate and conveniently a microscope slide, wherein multiple simultaneous tests are conducted on a single multifurcated testing sample. The plate or slide is partitioned into two or more testing zones with each of the zones having been preferably pre-loaded with a stable test reactant. The testing zones are physically separated from one another but are connected, with a fluid flow connection, to a single sample reservoir which simultaneously feeds, such as by capillary action, each of the testing zones with a test portion of the testing sample. The testing zones retain the individual portions for a time sufficient to effect the individual zone reactions with pre-loaded reagents. An optional outflow reservoir is utilized to capture excess sample flow and flushing fluids. Cell samples undergoing laser scanning cytometry are able to be simultaneously reacted, such as with varying fluorescent dyes, to provide a series of test profiles with a single sample and testing procedure.
