A modification of the classic haemagglutination inhibition method for immunoglobulin allotyping is described which employs reagent volumes of 2 microliters compared with the 25 microliter volumes commonly used in other serological allotyping methods. No loss of sensitivity or specificity was associated with the miniaturised method when compared to the standard tile technique. This method simplifies the large scale phenotyping and screening of sera and permits considerable savings of valuable reagents to be made.
