This involves a scratch test of the 60 most common foods and two controls, giving you a total of 62 scratches. EMLA will be prescribed and should be appropriately placed on the back from the top of shoulders to the waist, and then wrapped in saran wrap as described here prior to the appointment. During the visit, the patient meets with the nurse first. The saran wrap will be removed and the back cleaned with alcohol. Marker dots are then put on the back with a washable marker and the scratch test is performed. After all the scratches are placed, we wait 15-20 minutes to see if there is a hive next to the dots (which indicates allergy). The nurse will read the test and Dr. Pichichero will go over the results at the end of the appointment. Testing takes approximately 30 minutes.
