ABSTRACT:
An apparatus is provided for use in qualitative and quantitative determinations of agglutination in immunoreactive systems. The apparatus comprises a carriage assembly having a plurality of spaced, axially-disposed compartments for receiving image cells which are uniquely designed for holding the biological fluid test specimen and the reagent therefor. Means are provided for partially lifting each image cell successively out of its compartment and into an optical path. A monochromatic light source directs beams of radiant energy through the reaction zone in each image cell and the light beams transmitted through the reaction zone are focused, by means of an imaging lens, on the surface of an image sensor such as a "Charge-Coupled Device". The dark areas formed on the image sensor are measured electronically and also displayed on a display cathode ray tube.
