Correlation of MAST chemiluminescent assay (CLA) with RAST and skin prick tests for diagnosis of inhalant allergic disease.

The purpose of this study was to compare the new multiple allergosorbent chemiluminescent assay (MAST CLA) system with the RAST and skin prick tests as an adjunct to the diagnosis of inhalant allergies. In this report, MAST CLA and RAST have given similar results, but no technique is as sensitive as skin tests for allergen-specific diagnosis of inhalant allergic disease.
