Abstract
The invention is a novel immunoassay method for detection of the immunoglobulin IgA.sub.1 with O-linked oligosaccharides lacking sialic acid in fluid samples, such as blood, serum and plasma. Particuarly, the invention is an immunoassay method which extracts total IgA from fluid samples by reaction with an immobilized anti-IgA antibody, and then detects only the IgA.sub.1 fraction with labeled peanut agglutinin.
