A skin test or a blood test can be used to determine if you have a food allergy. A skin test includes putting a small bit of the questionable food on your skin and lightly scraping it with a specific needle. You're definitely allergic to something if you acquire a rash or a raised bump after consuming it. A blood test will look for antibodies linked to allergies in your blood.
The cost of a food allergy test is governed by a variety of factors, including the number of tests required and the tests themselves. Depending on the food or item being tested, a skin allergy test might cost anywhere from $60 to $300. A blood test might cost anything between $200 and $1000.
If you have health insurance, make sure to verify ahead of time to see if food allergy tests are covered. For example, your insurance company may cover skin allergy tests but not blood tests. You may have to meet your deductible before your insurance company pays for any tests. If you have any questions about the specifics of your policy, you may always call your insurance carrier.
If you have a skin test, you will have to wait in your doctor's office to see if you have any reactions. A wheal, which is characterized by a raised hump surrounded by a flare of red skin that can be itchy, will be examined by your doctor. In general, a large wheal and flare indicate a more severe allergic reaction. As part of a blood test, your blood will be submitted to a lab to be checked for immunoglobulin E (IgE) antibodies.
Expect to spend 20 to 40 minutes in your doctor's office for a skin test, during which a nurse or doctor will monitor your reaction. A blood test only takes a few minutes to draw a blood sample that will be sent to a lab for processing.
If you experience an allergic reaction to a specific food, a skin test can tell you immediately away. Although your doctor may advise you to stay longer in the office to ensure you don't have a significant allergic reaction, skin reactions normally occur within 15 minutes. The blood sample must be sent to a lab for analysis, and the results could take several days.
Many doctors' offices offer allergy tests, but it's usually advisable to contact a specialist. Doctors who specialize in the diagnosis and treatment of allergic illnesses are known as allergists. An allergist will collaborate with you to develop a treatment plan and, if necessary, prescribe medication if you test positive for a food allergy. Your primary care physician or your insurance provider can recommend you to an allergist.
Food allergy testing isn't an exact science. According to Food Allergy Research & Education, 50 to 60% of skin tests are false positives. That means that even if you aren't allergic to anything, you could have an adverse reaction to it. If you have a negative skin test result, your doctor may order additional tests to confirm the diagnosis. Falsely negative skin tests, on the other hand, are very rare.

Although there are home food allergy test kits available, they are not always accurate. Some home test kits look for antibodies other than IgE antibodies, which does not mean you have a real food allergy. Some home test kits may ask you to send in a hair sample, which is free of IgE antibodies as well. The best approach to get an accurate diagnosis is to schedule an appointment with an allergist.
Food allergies are a common occurrence. Food allergies affect 32 million Americans, including 5.6 million children, according to studies. One in every thirteen youngsters under the age of eighteen falls into this category.
Food allergies to shellfish, milk, peanuts and tree nuts, eggs, wheat, and soy are among the most common. Approximately 40% of children who have food allergies are allergic to many foods.
With time, some dietary sensitivities can be overcome. Milk, egg, wheat, and soy allergies, for example, rarely last into childhood, but some children may develop allergies to these foods after the age of five. Food allergies to peanuts, fish, and shellfish, for example, are often lifelong.
Food allergies can have serious, even life-threatening consequences. Hives, low blood pressure, difficulty breathing, a rapid pulse, nausea, and fainting are all symptoms of anaphylaxis, a severe allergic reaction. In a matter of seconds, anaphylactic reactions can occur. If anaphylaxis is not treated quickly, it can be fatal. Food allergy sufferers should have an epinephrine auto-injector with them at all times.
If you or your child suspects they have a food allergy, get a formal diagnosis as soon as possible so you can avoid the allergen. More than 15% of children with food allergies have had an allergic reaction at school, and up to 25% of epinephrine doses administered in schools are to children who are unaware they have an allergy. Knowing your child's food allergy allows you to tell school personnel so that they can be prepared if an allergic response occurs.
Food intolerances and allergies are not the same thing. Food allergies cause your immune system to overreact, causing it to release chemicals that make you sick. Food intolerances, on the other hand, can harm the digestive system and cause symptoms like cramps and diarrhea. Furthermore, because food intolerances do not elicit the same IgE antibody response as food allergies, they cannot be detected with a food allergy test.
