The Acousto-Optical Method for Blood Typing Based on Discrete Processing of Photographic Images

Abstract

This work is devoted to the development of the acousto-optical method for blood typing based on analysis of digital photoimages of sedimentation of red blood cells and their aggregates and immune complexes (agglutinates). Two modifications of the discrete method for photographic image processing were suggested and experimentally tested to increase the reliability of instrumental human blood typing. AB0 matching of blood samples was performed. It was shown that the proposed methods for discrete processing of photoimages provided a several hundredfold increase in the resolution of the acousto-optical method for blood typing as compared to the conventional photometric approach. The reliability of blood typing was also considerably improved.
