Abstract
An apparatus for judging an agglutination has a transparent plate stand 5 for supporting a microplate 7 and perforated with positioning openings 9 for centering of each well 8 of the microplate. A light source and TV camera 12 are disposed above the microplate, an image memory 13 stores the output of the camera, a processor 15 differentiates the stored image to determine its profile, and the picture elements of the differentiated image having intensity levels larger than zero are counted. A calculator 17 produces coefficients of variation, which are plotted against the image profile and compared with a reference value to remove contrast irregularities.
