title: [Use of proteases to improve the sensitivity of ABO antigen detection by absorption-elution test in analysis of human excretion traces].
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.
