People come to us from NJ, PA, and beyond because our board-certified allergists can truly change lives with our food allergy treatment.


Common Food Allergies

Symptoms of a Food Reaction

Allergic reactions to foods can range from mild to  anaphylactic. Mild symptoms can be treated with antihistamines, but severe reactions are life-threatening and require administration of epinephrine.  Anaphylaxis symptoms include the following:

  • Swelling of the face, tongue or airways.
  • Hives and flushing
  • Difficulty breathing
  • Dizziness
  • Stomach cramps
  • Nausea or diarrhea
  • Severe vomiting
  • Fall in blood pressure and shock

Food Allergy Testing

Is it a food allergy?

Food allergies affect 32 million people in the United States. Potentially life-threatening food allergies should be evaluated by a board-certified allergist who is able to choose the correct tests and knows how to properly interpret the results.

Obtaining a detailed medical history from the patient is an important first step in making a correct diagnosis. Our doctors will then run a combination of skin and blood tests to help determine the patient’s allergy profile. Skin testing for foods is simple and painless and is the most reliable diagnostic tool. It consists of a panel of foods applied via drops with superficial application on the skin. Results can be read within 15 minutes.  Blood testing adds important supplemental information.


Component Testing in Anaphylactic Food AllergyComponent Testing

If skin tests confirm an allergy, the next questions become, “Is this patient at risk for a systemic reaction like anaphylaxis, or can they actually tolerate the food, and therefore be a good candidate to proceed with an oral food challenge?” Component blood testing can offer helpful information to make a decision. This is because patients with allergies to peanut or tree nuts are allergic to different protein components in the allergen. The particular pattern of sensitivity can predict whether the child will have an anaphylactic reaction or only localized mouth itching.

For example, if a child is only allergic to Ara H8, component 8, of peanut, they will not have an anaphylactic reaction.  Egg component testing helps predict whether your child will tolerated baked egg goods as well as the likelihood of outgrowing the allergy. Milk component testing can provide similar information.  Component testing should always be done in the evaluation of anaphylactic food allergy and is part of the food evaluation that we do at Allergy Group NJ.



A Comprehensive and Personalized Food Allergy Treatment Plan

Once we’ve accurately diagnosed your condition, our adult and pediatric food allergists will work with you to create a personalized treatment plan. Depending on the severity of the condition, we may recommend food avoidance or a more proactive treatment like oral immunotherapy (OIT).

But your allergy care won’t stop there. We’ll provide ongoing education and teach you the skills you need to manage an allergic reaction, should one occur. We’ll also periodically re-evaluate and deliver necessary medical support along the way.

Managing Peanut Allergy And Other Allergies

Food Avoidance vs. Oral Immunotherapy (OIT)

Children typically outgrow food allergies such as milk and egg allergies. Severe peanut and tree nut allergies, on the other hand, can worsen over time and become lifelong conditions. In the past, strict avoidance of the food was the only option—but things have changed. At Allergy Group NJ, we can treat anaphylactic food allergies with oral immunotherapy (OIT), a process where you’re given the allergenic food in very small incremental amounts over time to decrease the reaction. Recent studies have shown that OIT is especially effective in young children and can induce remission in some.
