To compare the performances of the Phadiatop test and the RIDA qLine Allergy in specimens from the South Korean population.


We divided 430 consecutive patient specimens into 4 groups depending on the test results of the 2 assays. We evaluated the degree of agreement between the assays and used the ImmunoCAP sIgE test to identify the allergen-specific immunoglobulin E (IgE).


Agreement between the 2 tests was significant (k = 0.614, P <.001). When tested with the ImmunoCAP allergen-specific immunoglobulin E (sIgE) test, 8 of 48 (16.7%) cases that tested RIDA qLine Allergy positive/Phadiatop negative yielded positive results and 34 of 35 (97.1%) RIDA qLine Allergy negative/Phadiatop positive cases yielded positive results in more than 1 of the 14 tested items.


Our results suggest that the Phadiatop test is more accurate than the RIDA qLine Allergy in discrepant cases.
