[Comparative study of 2 in vitro screening tests for the diagnosis of allergy].

In 108 patients with inhalant disorders, atopy screening was performed with two in-vitro tests; Phadiatop (Pharmacia) and inhalant screening (IHS 1 and 2 discs) (Kallestad). Both tests are accurate and useful tools in differentiating atopics from non-atopics. In contrast to the Phadiatop the allergens on the IHS discs are known, and thus if the results are positive single RAST detection is possible.
