As soon as symptoms present themselves. Asthma can start soon after birth in some children and is usually well underway by the 5th birthday. Allergic diseases including food allergy may also start in infancy. Nasal and ocular allergies often start later and continue into adulthood.
What do I need to do to prepare myself for a first time visit in your office? How long does the visit take?
What method of skin testing do you use? Is it painful? Will it be done at the first visit?
Using up to date easily placed applicators, we can test for a variety of allergens. Small amounts of allergen solutions are placed on the back. Within 15 minutes we can tell you to which allergens you may be sensitive. Allergens available include pollens, mold, dust mites, animal dander and various foods. If necessary, venom skin tests will reveal sensitivity to insects. This is the most accurate test available. A short video demonstrating skin can be viewed by following by clicking Skin Test Video. The applicators will feel somewhat prickly during the second or two that it takes to apply. Often the skin testing is performed at the first visit and the results are incorporated into your treatment plan.
How long a waiting period do you have before there is an available appointment for a new patient?
Do I have to be referred by my physician?
Is Dr. Johnson board certified?
