Diagnosing Food Allergies
If you think you have food allergies or food intolerances the best advise we can give is to seek
diagnosis, we can pretty much guarantee your symptoms will not just go away. When your symptoms last longer than a week or two and tend to recur, you can use any of the following to diagnose which foods you are reacting to, then you know exactly what to avoid.
Tests that may reveal the specific allergens include:
Skin testing - the most common method of allergy testing. This may include intradermal, scratch, patch, or other tests. Skin testing may even be an option for young children and infants, depending on the circumstances.
Blood test - also called RAST (radioallergosorbent), this measures the levels of allergy antibody, IgE, produced when your blood is mixed with a series of allergens in a laboratory. If you are allergic to a substance, the IgE levels may increase in the blood sample. The blood test may be used if you have existing skin problems like eczema, if you`re on medications that are long-acting or you cannot stop taking, if you have a history of anaphylaxis, or if you prefer not to have a skin test.
‘Use` or `elimination` tests - suspected items are eliminated and/or introduced while the person is observed for response to the substance. This is often used to check for food or medication allergies.
Hair Test this test is quick, easy, painless and accurate. There are several different variations but we refer you to our Allergy Testing Pantry for options.
