Abstract
Two different house dust preparations (house dust and fractionated house dust) were compared using intracutaneous skin tests and RAST [radioallergosorbent test] assays in 91 patients suspected of house dust sensitivity. Total correlations of 54-64% (house dust) and 68-74% (fractionated house dust) were obtained. The positive/positive correlations were 52% (n = 66) and to 60% (n = 42), respectively. Seventeen patients were tested by nasal provocation (NPT) and 33 by bronchial provocation (BPT) using the same house dust extract. Correlations between NPT and skin tests and NPT and RAST were 42% and 47%, respectively, and between BPT and skin tests and BPT and RAST 56% and 57%, respectively.
