Do my Food Allergy and Food Sensitivity test results relate to each other at all?
Food allergies and food sensitivities may result in similar isolated symptoms such as nausea, vomiting, cramping, or diarrhea. The differences between the two types of reactions are important to understand and the results of one test, as well as other allergy tests, may not be the same.
In general, food sensitivity symptoms differ in severity and reaction time frame when compared to food allergy responses.
Food sensitivities involve immunoglobulin G (IgG) reactivity to certain foods. IgG reactivity is a response that typically causes delayed, non-life-threatening digestive symptoms or headaches.
Food allergies are immunoglobulin E (IgE) reactions that occur soon after ingesting certain foods. The immune response associated with food allergens can be life-threatening. Symptoms can include swelling of the lips, tongue, mouth, or throat, trouble breathing, or even shock.
Your healthcare provider may examine the results of your food allergy test or food sensitivity test as a first step when the type of allergy may be unclear. They will assess your symptoms along with your medical history to help create a plan that’s right for you.
