Abstract:
In order to determine the diagnostic performance of the Quidel Allergen Screen (QAS), 43 patients characterized by standard skin prick test and intradermal testing for atopic sensitivity were evaluated, in parallel, using Phadebas RAST and QAS to detect the presence of serum IgE. The Quidel Allergen Screen and RAST were compared with the investigator's clinical assessment. The differences between QAS and RAST are not statistically significant. The QAS appears to be equal to the Phadebas RAST in sensitivity and specificity and thus offers a rapid, easily interpreted in vitro method for the detection of specific serum IgE.
