Like any other test available, skin patch tests are not 100% accurate, which means at times, they can give what is known as a “false positive” or “false negative” result. The former suggests a contact allergy when the patient doesn’t have one, while the “false negative” result means that the test comes up negative, when indeed the patient is truly sensitive to the material. Nonetheless, patch testing is considered the gold standard when it comes to diagnosing contact allergies. Of course, it is imperative that our practitioners interpret the results to ascertain whether the patch test result truly explains your condition.
