Abstract

BACKGROUND: Phadiatop test which was developed for screening of atopy in eastern asia area, has not been sufficiently evaluated in Korea. In our previous study, the clinical usefulness of Phadiatop test for screening of atopy was evaluated on atopics and non-atopics defined by the results of skin prick tests with 10 inhalant allergens in Korea. In this study, we evaluated the usefulness of Phadiatop test for screening of atopy based on the level of CAP specific IgE in Korean asthmatics.
METHODS
On 136 Korean asthmatics, the level of CAP specific IgE to 10 important inhalant allergens and the level of Phadiatop specific IgE to mixture of 8 important inhalant allergens in Korea were measured. Atopics and non-atopics were defined by the results of CAP specific IgE and the sensitivity, specificity, predictive value of a positive and negative result, and concordance rate of Phadiatop test were estimated.
RESULTS
The sensitivity, specificity, predictive values of a positive and negative result, and concordance rate of Phadiatop test were 90.5%, 95.0%, 99.1%, 63.3%, and 91.2%, respectively.
CONCLUSIONS
Phadiatop test was very sensitive, rapid and convenient, and corresponded well to the results of CAP specific IgE. We concluded that Phadiatop test is very useful as a screening tool of atopy in Korea.
