Home tests for food allergies You can do immunoglobulin E (IgE) testing at home. This test includes a finger-prick kit so you can send in a small sample to a lab. This is a food allergy test that checks your IgE levels for a specific food.

Food Allergy Profile - This allergen-specific IgE panel is used to quantitatively measure an individual's IgE response to 15 different foods that are commonly associated with allergies.

Your allergist may recommend allergy tests, such as a skin test or blood test to determine if you have a food allergy. A sensitivity to a food can be indicated in a skin prick test or a blood test, but does not always show a true allergy unless there has been a previous reaction to the food.

The most frequently used food allergy diagnostics are the allergy skin-prick test and the allergy blood test. In a skin-prick test, a lancet is used to prick the skin under a drop of allergen extract. If a person is allergic to the allergen, a raised red bump will appear at the site of the prick after about 15 minutes.

Oral Food Challenge (OFC) is the most accurate test to determine whether you have a food allergy. It can also determine whether you have outgrown a food allergy. During an OFC, you will eat pre-measured doses of a suspected food allergen and be closely monitored in the clinic for any type of reaction.

A food allergy chart is a template that you'll use to record which foods on your menu contain one or more of the 14 named allergens. It can be tricky to remember all of them, so having a chart is extremely useful.

The 14 allergens are: celery, cereals containing gluten (such as wheat, barley and oats), crustaceans (such as prawns, crabs and lobsters), eggs, fish, lupin, milk, molluscs (such as mussels and oysters), mustard, peanuts, sesame, soybeans, sulphur dioxide and sulphites (if the sulphur dioxide and sulphites are at a ...

Skin prick tests are conducted in a doctor's office and provide results within 15-30 minutes. A nurse or the allergist administers these tests on the patient's arm or back by pricking the skin with a small, sterile probe that contains a tiny amount of the food allergen.
