A sensitive method for the detection of anti-A and anti-B hemagglutinins in fresh saliva has been developed. The method utilizes a bromelin treated erythrocyte suspension as indicator cells and includes a simple procedure to concentrate these hemagglutinins. Antiserum directed against immunoglobulin A enhances the hemagglutination assay. We find that these salivary hemagglutinins are present in over 90% of the population and that their titer remains stable over a period of two months. These hemagglutinins can be used to blood type the donor of a saliva sample and can be used in a confirmatory test that complements the commonly used absorption-inhibition test which is used to detect salivary blood group agglutinogens. In preliminary studies we have determined that hemagglutinins can be successfully isolated and analyzed from dried saliva stains.
