We will use a small, sterile lancet or ultra-fine needle to gently prick the skin under a drop of the suspected food allergen extract. If you are allergic to this specific allergen, a raised bump should appear within 15 to 30 minutes.
This common diagnostic test measures the level of the antibody known as immunoglobulin E (IgE) specific to a particular food. High IgE levels may indicate you have a food allergy.
You'll consume the suspect food in tiny, measured doses, starting with very small amounts that gradually increase. With each dose, we'll observe you for some time for signs of a reaction. This test is considered a highly accurate method of detecting or ruling out food allergies.
Basophil Activation Test (BAT)
This test helps diagnose food allergies by mixing a tiny amount of blood with a suspected food allergen (such as peanut or milk) to see if basophils are activated. This test is valuable because it can often distinguish a true food allergy from sensitization.
