If you have contact dermatitis, hives, or another skin irritation, it could be the result of an allergy. In order to give you the best treatment for your skin condition, it is important to see a doctor who can accurately diagnose the problem. Part of that process will likely be allergy patch testing. Here’s what you need to know about how to prepare and what to expect from the process.
Preparing for Patch Testing
There will be a bit of preparation before you go into the doctor for your patch testing. You will have three appointments in all. During the first appointment, you will need to tell your doctor about any medications you take, including over-the-counter medications, as some of these may interfere with the testing. Your doctor may recommend that you stop taking certain medications for a few days before and during the patch testing. You should also skip any doses of antihistamines.
Applying the Patches
During your second appointment, your doctor will place allergens on patches, which are then placed on your skin. Usually, the patches are placed on the arms or back. There will be bandages over the patches, and you will need to make sure that they do not get wet. You will then go home to wait for the allergen to have an opportunity to cause a reaction on the skin.
Removing Patches and Diagnosis
At the last appointment, the patches will be removed and the doctor will examine each area to determine if there was a skin reaction to the allergen. From this test, your doctor can determine all of the potential allergens that you come into contact with on a daily basis.
