Our immune system is designed to protect the body from infections. However, there are times when the immune system may mistake perfectly safe food for dangerous invaders such as bacteria or viruses. This abnormal immune response may then develop into a food allergy. A food allergy is usually characterized by an itchy mouth, rash, digestive complications or serious anaphylaxis. Some of the more common foods that may cause an allergic reaction include peanuts, milk, pineapple, eggs, wheat and gluten. Since these allergic reactions can range from menial to life-threatening, food allergy tests can help identify the source of these reactions. Priority Lab Testing offers both single and paneled testing to suit your specific needs.
