Abstract

A method and system for analyzing a solution for an agglutination pattern. The method comprises the steps of producing an illuminated image of the solution on an array of pixels, and assigning to each pixel in the illuminated image, a data value representing the intensity of the illuminated image on the pixel. Those data values are then processed according to a predetermined program to determine if an agglutination pattern is present and, if so, to classify that pattern into one of a plurality of predefined classes. With the preferred processing procedure, the pixel array is separated into a plurality of zones, and the data values for the pixels in each zone are processed according to a respective predetermined procedure to determine values for a predefined set of variables. Then, those determined values are processed to determine whether an agglutination pattern is present in the solution, and if so, to classify that pattern into one of the predefined classes.
