title: ABO blood groups in Peruvian mummies. I. An evaluation of techniques.
abstract: Blood groups of Peruvian mummies of known origin were determined by three different methods: agglutination-inhibition, induction of antibody production and mixed cell agglutination. The three techniques gave identical results, but the last two were useful in establishing the presence of H (O) antigen, while the first technique would not. The results indicate the presence of A, B, AB and O blood groups in America prior to known European contact. This suggests the need for a revision of concepts of blood groups in the American Indian.
