Where is a food allergy test done and how long does it take?

A food allergy test is only conducted by a doctor in his or her office. It usually takes between 5 and 7 minutes and is generally painless.

How is the food allergy test conducted?

To conduct this test, gelatin capsules are used which contain an extract of a particular food product that you are being tested for. Sometimes capsules contain a neutral substance that is also used for testing purposes. The result can be ready in as little as 5 minutes or as long as 7 days, depending on the complexity of the case.

Risks and complications involved

There is always a risk of very serious reactions that can be life threatening. These tests are not recommended without the supervision of a doctor. Other reactions such as nausea, diarrhea, runny nose and eyes are common as well in these tests. For the most part, however, the test is generally safe when performed correctly.

Other food allergy tests

* Food provocation test
* Food challenge test
* Indigestion test

The purpose of the above tests is to confirm an allergy connected to a particular food or food additive. These tests are used as a last resort should the above mentioned test not be enough.

Preparing for the food allergy test

* Avoid eating any food products that are the cause of the allergy.
* Do not consume antihistamines or any allergy drugs prior to the test.

This test is conducted by giving one an injection or asked to swallow a test capsule which contains the food ingredients that are being tested. One will then be under observation for symptoms which may appear within minutes or may take days.
To ensure the right results sometimes the test is conducted with neutral capsules thus, inducing the placebo effect; in this case neither the doctor nor the patient knows.

A food allergy test is most effective and reliable when performed with intake of the foods products as it follows the same course as usual. After the test you will wait for 20-30 minutes and test will be made for several reactions; in the case that symptoms appear, they will persist for several days. Depending on the results of the food allergy test you will be put on the needed medication and/or avoid the consumption of the food product. With the doctor’s help, you should be able to get your food allergies under control.
