Summary A comparison of the RAST (Phadebas®), skin prick test, nasal test and a history of hay fever was made in 141 subjects, eighty‐seven being prick test positive, with three concentrations of extracts of Sweet vernal ( Anthoxanthum odoratum ), Cocksfoot (Dactylis glomeratd ), Meadow fescue (Festuca elatior ), Rye ( Lolium perenne ), Timothy ( Phleum pratense ), Meadow ( Poa pratensis ). In adequate concentration any of the species extracts would have sufficed for skin tests, with Cocksfoot pollen the most potent. Correlations found were: positive RAST/prick test, 98%; positive prick test/ RAST, 89%; positive RAST/nasal test, 75%, and the higher the RAST the closer the correlation and the higher the nasal sensitivity; nasal test positive/RAST negative, 17%; positive history/RAST, 91%; positive history/prick test, 92%.
