Frequently Performed Testing

Skin Test:

Skin allergy testing is the most sensitive and accurate way to diagnose the cause of allergies. Skin tests are accurate for sensitivity to pollens, molds, pet dander, dust feathers, cockroach, foods and venoms of stinging insects like wasps and fire ants.

Solutions are extracted in a laboratory from an allergen (a substance which may cause an allergic reaction). The solution is then pricked or injected into the skin test site. Reactions occur within 15 minutes. Itching, redness, and swelling at the skin test site indicate a positive reaction.

Using these procedures in our office most people do not find allergy skin testing painful. We are usually able to test even young children without significant discomfort.

Prick Skin Test:

These tests may be done on the back or forearm. The area is cleaned with alcohol and marks are made on the skin with a pen to identify the various allergens. A small plastic device with a sharp point is dipped into an allergen solution and used to make a tiny prick of the skin. A separate prick is made for each allergen. Swelling and redness at each prick site is measured in 15 minutes.

Medications that interfere with allergy skin testing:

The following medications interfere with allergy skin tests and therfore SHOULD BE DISCONTINUED PRIOR TO TESTING.

1. Antihistamines
2. Antidepressants
3. Beta Blockers

Most medications do not interfere with skin testing, but you should check with our physician at least 5 days prior to your appoint ment.

Blood Tests:

Allergy blood tests can also be used to detect sensitivities. Blood allergy testing is most often done when a patient has extensive skin problems preventing skin allergy testing, or when a patient can not stop a medicine which may interfere with skin tests. This form testing is generally more expensive and usually takes 2 weeks to obtain results.

PFT (Pulmonary Function Test):

This is a painless strategy used to measure lung function. This test can determine whether or not you have any type of lung disease, such as asthma. It also determines your lung capacity and tells the physician if a current source of treatment is working.
