Do you think you may be allergic to a specific food? Food allergies are not uncommon, and many people have them without even realizing they are allergic to something. Come to Columbia Asthma & Allergy clinic today in Fremont, CA, for Food Allergy Testing. Not only will you know for sure what you are allergic to, but you might discover some foods you are extremely allergic to that you were previously unaware of. It’s best to get this information now rather than experience a surprise allergic reaction that could severely impact your health.
How do you test for food allergies?
There are a few ways we can test for food allergies at our allergy clinic in Fremont, CA. In most cases, a skin test is all we need to determine how allergic you are to food. Blood tests are sometimes required to confirm an allergic reaction if our doctors feel a skin test has produced a “false positive.”
What kind of skin tests do you perform at your clinic to determine food allergies?
Our facility can administer both patch tests and skin prick tests. These tests expose a tiny part of your skin to a liquid version of the food that is being tested. When we use skin prick tests, we inject a small amount of liquid just underneath your skin and wait for about 20 minutes for an allergic reaction. If positive, a little small red bump will appear as if a mosquito has bitten you.
For a patch test, we enclose a small part of your skin with a patch containing an extract of the food we are testing for an allergy. While this method does not require your skin to be pricked, we must wait two weeks for the results. Both of these food allergies tests are very reliable!
What happens after my food allergy test?
Our board-certified providers usually only need a skin test to rule out food allergies. If your skin does not react to either the patch or skin prick test, you are very likely not allergic to a food. However, a reaction on the skin doesn’t always mean someone is allergic to a food. When this happens, it is called a “false positive.” It often occurs when the test gives a positive result, but a patient has never shown any symptoms of being allergic to the tested food and possibly has eaten the food for years. To confirm an allergy or the lack of one, a follow-up test will be needed to be sure. This is known as a food challenge. This test will have a patient eat or drink small amounts of food in increasing quantity. Under the careful supervision of our allergy specialist, for the safety of the patient, we will see if any allergic reaction appears. If no symptoms present themselves, then we know it was a “false positive.”
How can your allergist figure out which foods make me sick?
This may surprise you, but it can be challenging to determine what foods make you sick. Some allergies present themselves right away, often in the form of a rash that develops when someone is exposed to it. However, in some cases, symptoms may only appear hours after exposure. This delay often makes it difficult to track down what food is causing an allergic reaction.
The allergists at our Fremont, CA location will talk with you one on one to diagnose your food allergy. They will ask you a variety of questions and review your medical history as they determine your food allergy. Some of the things they will want to know include:
- What are your symptoms?
- How often do they appear?
- Does it depend on the amount you eat?
- How long does it take for symptoms to appear?
- How long does it take for your symptoms to go away?
Will I have to go on a special diet?
A special diet is usually only needed when your food allergy is difficult to identify. You’ll be asked to keep a detailed diary of the food you eat and the amounts. If you experience an allergic reaction, a detailed description of your symptoms will be needed. A special diet allows our specialists to pinpoint the food that is causing you problems. We will have you avoid suspected foods for a few weeks until your symptoms go away and then try some suspected foods in a controlled setting. If symptoms appear, we have found the culprit.
Testing for food allergies with a special diet should never be done without the guidance of one of our allergists. It could be very dangerous to your health if this is done unsupervised.
