Would help if did: Many times timing and distribution (where and when) of the rash will give you the answer. Most don't need biopsies. Typically symptoms occur hours or days (not minutes) after exposure. TRUE tests are good basic patch tests, but ask about higher level (NACDG) testing if insufficient. Side effects? Causing the exact same rash that caused the visit (usually placed on the back).
