The Components of Food Allergy Testing for Adults and Children

Food allergy reactions can vary from some mild discomfort to life-threatening symptoms. The risk of ignoring any symptoms can be severe, particularly for young children who are susceptible to food allergies.

Food Allergy Testing and Treatment

Identifying a food allergy allows a sufferer to seek food allergy treatment and/or make conscious decisions regarding their dietary habits. Chacko Food Allergy Treatment Center offers three food allergy testing options to families in the surrounding Atlanta area.

Food Allergy Testing Options

If you suspect you or your child have food allergies, it is important to get tested. The testing options depend on both the type of allergy and the individual patient. Here’s an overview of the food allergy testing options available at our seven food allergy treatment centers.

Skin Prick Test

A skin prick test is commonly used to determine food allergens. A solution containing the food or other substance suspected of causing the allergy is placed onto the skin. Sometimes, the food itself may be used. The skin is then pricked with a needle or scratched to allow the solution to enter just below the surface. The allergist will check for the appearance of a raised bump to indicate signs of an allergy.

Blood Test

A blood test involves taking a blood sample for laboratory analysis. The test will search for an antibody called immunoglobulin E (IgE). This antibody is produced in response to allergens and is usually higher in people with allergies.

Oral Challenge Test

The oral challenge test involves consuming small amounts of food while an allergist monitors your responses. This type of test will be conducted under supervision at one of our locations in Alpharetta, Atlanta, Canton, Cumming, Druid Hills, Duluth or Johns Creek.

Once you meet with one of our allergists and it is determined which food allergy test is best for you and/or your child, you’ve started on the path to peace of mind and greater freedom. Request an appointment today and take the first step.

Common Allergies Diagnosed With Food Allergy Testing

While food allergy testing can be used for all types of food, the vast majority of allergies are triggered by only a small number of food proteins. An allergist will discuss your symptoms and relevant medical history to determine which foods to test for. Overall, most people’s allergies are caused by the following eight food groups.

  • Peanuts – As one of the most common food allergies in children and adults, peanuts can cause severe allergic reactions.
  • Tree nuts – A tree nut allergy can involve an allergic reaction to walnuts, Brazil nuts, almonds, pecans, cashews, hazelnuts and pistachios. Patients might be allergic to only one tree nut, or to many.
  • Shellfish – Crustaceans include lobster, shrimp, crab, prawn and crayfish. Mollusks include squid, clams, oysters and scallops. Food allergy testing can determine which shellfish family you’re allergic to.
  • Fish – A fish allergy is not an allergy to shellfish, and typically involves cod, salmon, tuna, catfish, halibut and trout.
  • Eggs – Egg is a common allergy in young children. Food allergy testing (usually skin or blood tests), along with examining patient medical history helps diagnose an allergy.
  • Milk – For most people, cow’s milk is the usual cause of a milk allergy. However, sheep, goat and other milk types can also lead to allergic reactions.
  • Wheat – If you experience allergic reactions after eating items like bread, pasta and cereal, you may have a wheat allergy.
  • Soy – Soy allergies usually start at a young age. Thankfully, this type of allergy is often outgrown before a child reaches their teenage years.

Food Allergy Testing Is the Starting Point

At Food Allergies Atlanta we receive all types of questions about food allergies and how to treat them. The most common questions and answers are included below.

What is the best food allergy testing option?

A skin test is the most common option and it’s very accurate. However, certain skin conditions or medications may require another type of test. Because each patient is an individual, an initial discussion with an allergy doctor can identify the most suitable option.

What are the symptoms of a food allergy?

Common symptoms include difficulty swallowing, an itchy mouth or throat, breathing problems, swelling in the mouth, face or throat, skin swelling and dizziness.

Can a child receive food allergy testing?

Food allergy tests are suitable for children of all ages. However, it is important to discuss any medications or medical conditions with your allergist before proceeding.

Schedule a Food Allergy Test Today

Speaking to an experienced allergy doctor allows you and/or your child to discuss common symptoms experienced when eating particular foods and to share family history of allergic reactions. The doctor will then help you explore current food allergy treatment options such as oral immunotherapy. Our allergists can determine the best course of action for identifying and treating a food allergy.
