[Intracutaneous tests with phytohemagglutinin for detection of cell-mediated immunity (author's transl)]

Patients with various forms of dermatosis and healthy control subjects were simultaneously tested intracutaneously with specific antigens (candidin, trichophytin, kabikinase, tuberculin and the mumps skin test antigen) and the non-specificmitogen PHA-P. A positive delayed reaction was observed in 98% of the healthy subjects and 76,6% of the dermatosis patients following intracutaneous application of 2 microgram PHA-P.--The results of these studies suggest that the PHA-P intracutaneous test might be suitable as a screening method for diagnozing cellular immun-defects.
