This invention relates to clinical diagnostic assays, related optical bio-discs,
and a disc-reading apparatus. The invention is directed to methods and apparatuses
for performing immunohematology assays using an optical bio-disc analysis system.
The invention is further directed to an optical bio-disc for performing an immunohematologic
assay including a substrate having encoded information associated therewith. The
encoded information may be readable by a disc drive assembly to control rotation
of the disc. The disc may also include at least one target zone or capture zone
associated with the substrate. The target zone is disposed at a predetermined location
relative to a center of the substrate. The disc further includes a plurality of
capture antibodies immobilized within the target zone, a flow channel, fluidic
circuit, or analysis chamber associated with the target zone, and an input site
in fluid communication with the analysis chamber.
