This paper reports a new horseradish peroxidase enzyme linked immunosorbant assay (ELISA) to detect patient serum alloantibodies. The new methodology utilizes a water-soluble chromogen, O-dianisidine and a temporary solid antibody support, osmotically lysed reagent erythrocytes. In a double blind study the horseradish peroxidase ELISA was found to be as sensitive as the conventional antiglobulin test. In parallel dilution studies on serum samples containing anti-Kell antibodies, the horseradish peroxidase-ELISA was found to be substantially more sensitive than the conventional antiglobulin test. While the procedure is at present impractical for routine use, these results indicate a potential for improved sensitivity which warrants further research. Possible applications and prospective areas of research are discussed.
