In some people, exposure to certain foods, can cause allergic reactions.

In some people, exposure to certain foods, such as nuts, shellfish, and soy products, can cause allergic reactions. The symptoms can range from mild problems to a life-threatening allergic reaction called anaphylactic shock. Therefore, if you think that you may have allergies to a food, it’s vital to have an allergy doctor in Las Vegas determine what you’re allergic to. There are several safe and effective ways that a doctor can diagnose a food allergy to provide relief.

Food allergies affect both adults and children and some of these patients may have life threatening reactions to foods. A skin test combined with a medical history may be an essential first step to treating food allergic conditions.

FOOD TESTING

Prick skin testing, also known as scratch testing, is one type of food allergy test. A small disposable prick device applies the allergy extract to the skin by scratching or pricking the skin. A hive or raised bump may occur at the site of the prick test. Each test site will be measured and compared to a positive and negative control allowing for specific allergies of the patient to be identified. Prick testing may be applied to the forearms or the back depending upon the age of the patient, the number of tests ordered, and the condition of the skin. Results occur, typically between 10-20 minutes.

Another test for foods, if indicated, is an oral food challenge which is performed in the medically safe environment of an allergist office. The patient generally brings a single food item into the office and it is given under the supervision of the doctor. Patients are monitored during this time for any signs of a reaction.

Another type of testing known as a RAST or Immunocap testing involves examining specific IgE in the blood. The benefit of this test is it involves a single needle stick and results are typically obtained within a few days.

Identifying a Food Allergy

Sometimes, it’s easy to identify a food that you are likely allergic to, such as if you break out in hives or a rash after eating peanuts or shellfish. Other times, the source of your allergic reaction may not be so exact. In that case, an allergist will examine your medical history, ask about your family history of allergies, and ask you relevant questions including:

  • Your symptoms

  • When the symptoms occur

  • The quantity of food you consumed

  • Which foods you ate before the reaction

  • The frequency of the reaction

  • How long the reaction lasts

Testing for Food Allergies

To confirm a food allergy and help determine what exactly you’re reacting to, your doctor will likely perform one or more types of allergy tests. One of the most common tests for food allergies is a skin allergy test. A skin test is a quick and safe way to pinpoint a food allergy. For this test, your doctor will put small samples of potential allergens on your skin, followed by slightly pricking the skin. It usually takes about 15-20 minutes for any reaction to occur, which confirms an allergy. A blood test or food challenge may also be used.

To get relief from your food allergy and asthma symptoms, don’t hesitate to contact Dr. Tottori’s office today by calling (702) 240 4233 or scheduling an appointment online.
