Allergy skin test is used to detect if you are sensitized to or allergic to certain allergens so your physician can formulate an effective treatment to your allergy / sinus, asthma, and other allergy related diseases. At Texas Allergy, we test for common regional environmental allergens including pollens, grasses, weeds, molds, and indoor allergens like cats, dogs, dustmites, cockroach, rodent, and other cattle allergens. In general, you are exposed to high tree pollen concentration in the Spring, grass in the Summer, and weed pollen in the Fall season. Mold spores and indoor allergens like cat/dog/dust mites are all year-round allergens. Depending on indications, we also test for foods, insects, drugs and other allergens. Skin test is done by pricking the skin in the back or forearm with a small plastic device containing specific allergens to challenge the allergy cells living in your skin. The prick site will develop a small mosquito-like wheel if you are allergic to that allergen. Sometimes, your physician might proceed with a second intradermal allergy test if the first test is negative. In this type of test, a small amount of allergen is injected into your skin to increase sensitivity of the test.
