A simple method to detect AB antigen in blood grouping of body fluid stains.
A modified mixed agglutination method is described for detecting AB antigen from body fluid stain. Saline extract of body fluid stain was added to A.Se saliva stain which was beforehand sensitized with anti-A. AB antigen reacting with the stain was detected with the usual mixed agglutination method using anti-B and B red cells.
