ALLERGY TEST - VEG + POLLENS + CONTACTS + DRUGS

You should get a veg + pollens + contacts + drugs allergy test if you have multiple or unexplained allergy symptoms, such as sneezing, wheezing, hives, eczema, reactions after certain foods, or a past reaction to medicines. It is also recommended for asthma, before surgery in people with suspected drug allergies, and before immunotherapy.

No special preparation or fasting is required for a veg + pollens + contacts + drugs allergy test. Antihistamines do not affect this blood test, so you can usually continue them. Never take a suspected drug or food just to test it. Bring details of past reactions, and inform your doctor about steroids or omalizumab.

No, fasting is not required for a veg + pollens + contacts + drugs allergy test. You can eat and drink normally before giving your blood sample, though you should avoid foods or medicines you already suspect cause reactions. You can usually continue antihistamines, as they don’t affect this blood test.
