title: The RIDA Allergy Screen Versus the Phadiatop Test in 430 Consecutive Patient Specimens.
abstract: OBJECTIVE
  To compare the performances of the Phadiatop test and the RIDA qLine Allergy in specimens from the South Korean population.
  
  
  METHODS
  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).
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  Our results suggest that the Phadiatop test is more accurate than the RIDA qLine Allergy in discrepant cases.
