Fifty pollinosis patients, who have reported contact with P. officinalis, were tested for skin sensitivity with P. officinalis pollen extract. Intracutaneous testing and the skin prick method were employed and their sensitivity verified with regard to serum concentrations of specific IgE antibodies determined with the RAST method. Two criteria of the skin prick method evaluation were employed. The intracutaneous method correlated best with RAST. In contrast to intracutaneous testing, the skin prick method did not produce any false-positive results; however, due to a few false-negative cases observed, it appeared that in borderline-negative cases the skin prick method would require determination of serum IgE antibodies to reach a clear-cut diagnosis.
