Detection of Immune Anti-A and Anti-B Allo-Antibodies with Groupamatic® System

Abstract
An inhibition technique using soluble AB group substances for screening of 'immune' anti-A and anti-B allo-antibodies has been set up on Groupamatic. This screening is performed on all blood units of group O, A and B to be transfused. The ratio of potentially dangerous donors in case of non-isogroup transfusion is 2.86% of the total number of screened donors. This detection is performed simultaneously with other immunohaematological and serological tests: ABO and Rh grouping, screening of irregular allo-antibodies, screening of syphilis.
