SCRATCH TEST/PRICK TEST
FOY, MD utilizes scratch testing—also known as “prick testing”—to apply allergens directly to a shallow scratch on the skin, inducing an IgE reaction. Offending allergens produce a wheal (a raised, red area similar to a mosquito bite) in varying sizes depending on the severity of the reaction. These reactions are measured to determine which allergens a patient is most sensitive to and then utilized to create the patient’s own unique Immunotherapy.
The test results are available within 10 to 15 minutes and reflect more sensitive allergies that may not be shown on blood tests, therefore yielding more complete results. Patients can physically see almost immediately exactly what is giving them their runny nose and itchy eyes.
