In studies made by researchers in the laboratory during a period of several years, wholly microbic antigens and their separate chemical fractions were used for skin tests. With these antigens they studied the reactions of the blast transformation both in vitro experimentally and in patients. The data obtained indicate that skin tests have diagnostic value only in those cases where the dosage of antigens was correctly selected and where only the sharply positive reactions were considered. Since sensitization to microbic antigens is often detected among healthy people, the use of large doses of antigens produces a large percentage of falsely positive reactions.
