Isoagglutinin Titer, Anti-A, Serum
Use
Isoagglutinin Titer, Anti-A, Serum is useful for evaluating individuals with possible hypogammaglobulinemia. It aids in the investigation of suspected roundworm infections. Isoagglutinins are antibodies produced by individuals causing the agglutination of red blood cells in others. They are directed toward A or B antigens absent in their own RBCs, typically formed in response to exposure to A-like antigens found in microorganisms.
