Abstract
An assay for determining the Lewis blood group of a patient consists of testing a body sample for the presence of Lewis.sup.a and Lewis.sup.b antigens. Monoclonal antibodies specific for either of these antigens are employed which do not cross-react with other related antigens, such as the H blood antigen. Body samples which may be tested include: saliva, serum, urine, and paraffin-embedded tissue samples. Hybridoma cell lines and the antibody compositions they produce specific for these antigens are provided for use in the assay.
