Care4U is now offering allergy testing every Friday. Allergy testing consists of a quick, painless skin-scratch test that tests for 72 common allergens in the south Texas area, such as molds, plants, animal dander, and even food allergens. Based on your results, the doctor may recommend allergy desensitizing shots, which are meant to slowly expose the body to allergens until immunity to the allergen is met, possibly decreasing the need for long-term antihistamine medication and improving one's quality of life. Shots are also available at Care4U. Many insurance plans cover allergy-related services.
