Patch testing is a method used to determine whether a specific substance causes allergic inflammation of a patient’s skin. Any individual suspected of having allergic contact dermatitis or atopic dermatitis needs patch testing. Dermatologists apply patch tests in patients with dermatitis, to find out whether their skin condition may be caused or aggravated by a contact allergy. Patch tests are used to identify the cause of contact allergic dermatitis.
How does Patch Testing work?
The test panels will be placed on a spot, most likely your back, and you will need to wear them for 2 days. After 2 days, you will return to the office to have the panels removed. When the panels are removed, some reactions may be visible on the skin. Two days later you will return to the office again for your second reading. Your doctor will determine if it is necessary to perform additional readings after your second reading. This additional reading can help distinguish between true allergic reactions and irritant reactions. Your patch testing results will be discussed at your final visit.Contact Us
