Abstract:
BACKGROUND: Irregular antibodies are antibodies that are not regularly present in the serum of particular blood groups and its presence results in many problems including HDN (hemolytic disease of newborn) in transfusion medicine. Column agglutination test was recently introduced and has been widely used for advantages of standardized working procedures, standard reactions, stable reactions for hours and Coombs test without washing steps. We tested irregular antibodies in cord blood by column agglutination test and investigated its incidence and relation with HDN. METHODS: We tested the cord blood collected during delivery from 200 pregnant women. Column agglutination test was done on DiaMed ID MicroTyping System (DiaMed, Switzerland) and both LISS/Coombs and NaCl/Enzyme ID-cards were used. The antibody screening test was done first and antibody identification test was done to positive cases in same way. The cell typing and Rh phenotyping for cord blood of positive cases were also done. RESULTS: 2 cases of 200 samples (1%) were positive in the antibody screening test and each was identified as anti-D and anti-E antibody. CONCLUSIONS: Irregular antibody screening in cord blood by column agglutination test is thought to be helpful in early diagnosis and treatment of HDN.
