Skin allergies are just one type of allergic reaction. They can vary from annoying to dangerous, but no matter the scale of the allergic reaction, the first step to take is still the same. Patients need to head to an allergist for skin Allergy Testing in Evansville IN. It may sound intimidating, but patients who suffer from skin allergies need to know what is triggering the reaction to avoid future flare-ups. Knowing what to expect can help some patients feel more comfortable with the process, so read on to learn more about three different kinds of skin allergy testing.
Scratch Tests
Scratch tests are sometimes also known as prick tests or puncture tests. Don’t be intimidated by the name, though. They are entirely safe. First, a medical professional will examine the skin on a patient’s forearm or back. The area being tested on will be cleaned with alcohol and then marked and labeled with a pen. A small drop of each potential allergen, usually in the form of a concentrated liquid extract, will be applied to each of the marked spots. Next, the outer layer of skin will be lightly scratched to allow the allergen to penetrate. The process may be mildly irritating, but it won’t be painful or draw any blood.
Intradermal Testing
In intradermal testing, the concentrated liquid allergen is injected directly under the skin. After about fifteen minutes, a health care professional will then examine the area to look for a reaction. Patients who experience anxiety around needles may want to discuss alternative testing procedures with their doctors.
Patch Testing
A patch test is one of the most comprehensive forms of Allergy Testing in Evansville IN. It requires two separate visits to the doctor scheduled about 48 hours apart. During the first visit, a health care professional will place a potential allergen directly onto a patch and then stick it to a cleaned patch of skin on the arm or back. Patients must then wear the patch for up to two days as per their doctor’s instruction. This kind of allergen testing accounts for delayed responses.
