At Premier Allergy, Asthma and Sinus Care, we can skin test 90 environmental species and 90 foods at your first visit. Expanded testing may be available in special cases. This procedure consists of small amounts of protein from each allergen to be placed on the most superficial layer of skin to determine the extent of your body’s allergic response. Your results will be reviewed with you at the time of your visit by the provider. Check with you insurance regarding allergy testing costs as this can vary with each plan. To skin test, you must be off of all antihistamine containing medications for at least 4 days.
