Abstract
A clinical diagnostic assay is performed on an optical bio disc and is read with a disc drive. More specifically this invention relates to capture layer assemblies for cellular assays using optical bio-discs. The current invention includes methods for determining the quality and quantity of a specific type of cell in a biological sample. These methods includes binding capture agents to a capture zone on the disc, providing a sample to the capture zone, remove portions of the sample that are not bound in the capture zone, and counting bound cells. The current invention also includes methods and apparatus for performing a cluster designation marker assay using an optical disc and disc drive and method for making optical analysis discs for performing such cluster designation assays.
