| Abstract: | The highest sensitivity of the absorption-elution test for detection of A, B, and H antigens in human excretion traces was observed when the excretion traces were treated with protease C and lidase (hyaluronidase) and standard erythrocytes for analysis of the resultant eluates were treated with protease C. Cross-reactions of sera with antigens of contralateral specificity were ruled out by simple dilution of the sera; the reliability of antigen detection was not lost due to pronounced increase in the sensitivity of modified absorption-elution test. |
