DISPENSING OF A DIAGNOSTIC LIQUID ONTO A DIAGNOSTIC REAGENT

Biological fluid samples are deposited by methods that produce a uniform layer of the sample over a reagent-containing surface. In one embodiment, a nozzle having multiple openings is used to deposit a sample over the reagent-containing surface simultaneously. In an alternative embodiment, single dr...

Summary:Biological fluid samples are deposited by methods that produce a uniform layer of the sample over a reagent-containing surface. In one embodiment, a nozzle having multiple openings is used to deposit a sample over the reagent-containing surface simultaneously. In an alternative embodiment, single droplets of the sample are deposited in a pattern on the surface, preferably in a sequence of parallel lines. The reaction between the biological sample and the reagents is read from a spectrographic image of the reagent-containing surface obtained by optical methods.
