Its a food allergy test that tests for 113 different foods. I think the website is yorkallergyusa.com but Im not sure at the moment. They send you the kit to your house and its a finger prick test that you do yourself and then mail it back to them. The bad part is the price though - I just ordered it last week and I think it was $379.00 but Im desperate to get better right now! Ill let you know how it goes!
