How to Prepare for the Test?
Before any allergy testing, the health care provider will ask for a very detailed medical history. This may include questions about such things as illnesses, emotional and social conditions, work, entertainment, lifestyle, foods, and eating habits.
If skin testing will be performed, it is essential to take no antihistamines prior to the test, as this may lead to false negatives, and hence false reassurance that a substance is unlikely to cause a severe allergic reaction. Your doctor will provide the relevant information on which medicines to avoid and when to stop taking them prior to testing.
