Frequently Asked Questions
What allergies can be tested?
We test for food allergies (nuts, dairy, gluten, shellfish), environmental (pollen, dust, mold), and pet allergies.
Do I need to stop antihistamines before allergy testing?
For blood-based IgE testing, you do not need to stop antihistamines. This is an advantage over skin prick testing.
