Patch testing is performed for evaluation of allergic skin disorders known as allergic contact dermatitis. This test involves applying the test substance to the back with hypoallergenic tape and leaving it in place for 48 hours.After the test patch is removed from the back, you will need to return in 48 and 72 hours to read the test site. A positive reaction results in a localized rash at the test site. A positive test allows us to advise you on how to avoid what you are allergic to.
