Abstract
A new serological technique was introduced into blood grouping of blood-stains and other test specimens. In this method, latex-adsorbed agglutinin was prepared by mixing polyvinyl-toluene latex particles of 2.015μ in diameter with antiserum. Accurate blood grouping was possible with the agglutinin-adsorbing latex particles directly even on a small piece of blood-or saliva-stained fibrils in only about ten minutes. The described technique was recommended for wide use not only in blood group determinations, but also in general serological tests.
