What is the difference between a food sensitivity test, a food allergy test, and this indoor and outdoor allergy test?

Food sensitivity tests measure your Immunoglobulin G (IgG) reactivity to certain foods. IgG reactivity is a type of immune response that typically causes delayed, non-life-threatening symptoms. You can learn more about our Food Sensitivity Test and our Food Sensitivity Comprehensive Test.

Food allergy tests measure your Immunoglobulin E (IgE) reactivity to certain foods. The immune response associated with food allergens can be life-threatening because symptoms are typically associated with the digestive system. Symptoms can include swelling of the lips, tongue, mouth, or throat, trouble breathing, or even shock. This type of testing is typically performed under the care of a physician due to the serious nature of the immune responses that can occur. In severe cases, treatment may require a prescription.

This Indoor & outdoor allergy test measures your Immunoglobulin E (IgE) reactivity to certain indoor and outdoor allergens. This test does not measure your response to foods. The immune response associated with these allergens is known to cause cold-like symptoms, such as a runny nose, itchy eyes, cough, or headaches. Although reactivity level can’t predict how you will respond to the allergen, this information is a good step toward understanding which allergens may be causing unwanted symptoms, so you can better prepare for the season or make improvements to your home.
