Abstract
Apparatus for automatically typing HLA (Human Leukocyte Antigen) is disclosed. An optical image of a sample containing lymphocytes is formed by a phase-contrast microscope. The optical image is transformed into electrical picture signal through a image pick-up unit which in turn is transformed into binary picture patterns for a predetermined area site in the image through a window circuit. The obtained binary picture patterns are compared with template patterns of predetermined features corresponding to reacted and non-reacted lymphocyte images to detect and type the lymphocyte image. With this typing apparatus, HLA typing test can be conducted automatically with high accuracy.
