[A method for treatment of partially haemolysed blood with lost agglutination properties, allowing its blood group determination (author's transl)].

A method for treatment of partially haemolysed blood with lost agglutination properties is described, which allows a direct determination of its blood group. The method is based on the phenomenon of reversible agglomeration of erythrocytes after treatment of the blood with nonelectrolytic and electrolytic solutions. This phenomenon is well known in modern transfusion haematology (Huggins C. E., 1963). This method has been tested on 156 blood samples with anti-A, B and AB serums and on 47 blood samples with anti-A, B, AB and H serums, as well, with very good results.
