Correlation of allergy test results obtained by IgE FAST, RAST, and prick-puncture methods.
Prick skin testing and IgE FASTTM results were compared in eight atopic patients, using a comparable class system. Identical results were found in 53.5% of the cases; a total of 85.7% of the results were within one class difference. Sera from 436 patients were assayed for specific IgE to 94 allergens for a total of 436 test comparisons using IgE FASTTM and modified RAST. Identical results were found in 41.7% of cases; a total of 81.4% of the tests differed by one class or less. The IgE FAST showed good correlation both with prick testing and modified RAST. IgE FAST appears to be a valid non-radioactive, time-efficient method for detecting specific IgE to common inhalant and environmental allergens.
