Hagop Bessos

A competitive binding assay kit and process for the immunological detection of a blood antigen of specified phenotype (for example phenotypes of human platelet antigen HPA) in a sample of whole blood. The kit contains a substrate having purified blood antigen of specified phenotype immobilized thereon, antibody specific to said blood antigen and means for enabling detection of antibody bound to said blood antigen. The process comprises mixing a sample of whole blood with a predetermined amount of antibody, so as to bind the antibody to any antigen present in the sample of whole blood and bringing the mixture into contact with the immobilized antigen so as to bind any remaining unbound antibody to the immobilized antigen, and determining the amount of immobilized complex and consequently the specified blood antigen phenotype.
