title: Comparing the enzyme allergosorbens and coated allergen particle tests for latex allergy: which in vitro test should be chosen by an anesthesiologist?
abstract: To determine sensitivity and specificity of the enzyme allergosorbens test (EAST) and the coated allergen particle Test (CAP) in detecting specific antibodies against latex, we compared these two methods in a previously investigated sample of an epidemiological study among our anesthesia staff. One hundred one blood samples were tested with EAST and CAP for specific antibodies against latex. Skin test results were used as references. CAP was more sensitive in detecting sensitized individuals than EAST (56% vs 18.8%). Two additional persons with previously negative skin tests were detected. These results suggest that the EAST system is not as sensitive as the CAP system. Therefore, the CAP system should be preferred for the in vitro diagnosis of latex allergy.
  
  
  CONCLUSIONS
  Testing for latex allergy requires time-consuming and technically difficult tests. Easy to perform in vitro tests for latex allergy are desirable. Our results indicate that the coated allergen particle test is more sensitive and easy to use than the enzyme allergosorbens test.
