Food sensitivity testing is often done after someone has experienced symptoms of an adverse food response. Depending on the foods eaten before they occurred and the reactions they cause, certain tests may be ordered to search for particular food intolerances, allergies, or sensitivities. Most of the time, these tests are performed by the individual themselves. However, in more difficult cases where there is a strong likelihood of an allergic reaction to food, a specialist may be needed. This can occur when a person is suffering from eczema or asthma and it affects their ability to eat a normal diet. This is not always the case, but is something to consider if you are eating out at a restaurant.
There are a number of different types of allergy testing used to identify foods that may cause problems. One of the most common is called ELISA testing, and is usually used by those with egg allergies. An enzyme challenge is another common procedure, which is done by exposing the patient's body to various allergens. This exposes the immune system to different proteins that it is typically sensitive to. Sometimes food-testing procedures are combined with other allergy tests to ensure the results accurately reflect what may be causing the individual's symptoms.
There are a number of different sensitivities to foods, and most of them have similar symptoms. Blood tests are among the most common tests used, determining the individual's levels of IgE, which is a substance found in saliva. It is possible for people to be allergic to a wide variety of substances, and these tests can help rule out some of them. These blood tests are also great for those who suffer from chronic illnesses like diabetes, hay fever, asthma, and food allergies.
Food intolerances are another common testing result for those who have extreme food sensitivities to certain foods. Some examples of intolerance to food include lactose intolerance, shellfish allergic reactions, food allergies, and food sensitivities to the sun. A series of tests called a patch test can determine if you have any food intolerances or sensitivities, using spit as a way to collect samples.
At-home food sensitivity tests are available for those with extreme food sensitivities. These tests provide results almost instantly so you can begin treatment right away. They are usually fairly simple, requiring only a small amount of spit to collect the samples, depending on the specific type of allergy testing. The most common test involves applying a small drop of a solution containing allergen to the area being tested, while the patient lies down.
Food intolerance tests are also available through the American academy of immunology. This test allows allergy sufferers to determine their level of tolerance to different foods. It doesn't actually test for any allergies, but rather examines how the immune system reacts to foods. There are three categories of immunology that include food intolerance, food sensitivity, and food hypersensitivity.
Food allergy testing through the American academy of immunology can help you learn more about your own food sensitivities, whether you suffer from an actual allergy or not. These allergy tests not only examine your response to foods, but also your ability to function while consuming specific foods. This information is important for those who are suffering from autoimmune disorders, the diseases that can result in symptoms similar to those of allergies. Some examples of disorders related to the immune system are lupus and diabetes.
If you suspect that you have food sensitivities or allergies, consult with a doctor. If you do experience an allergy, you can take steps to control it by using certain medications and taking extra precautions. If you've eaten a particular food and experienced adverse reactions, it's important to report your findings to your doctor. A food intolerance is more complicated and requires stronger actions to combat.
