Patient Experience and Quality of Patch Testing on the Legs vs Back

Description

The gold standard for the diagnosis of allergic contact dermatitis is patch testing, during which allergens are affixed to the skin underneath tape and left for multiple days. A large area of clear skin is thus required for successful testing. While the back is traditionally thought to be the ideal area for testing, the thighs may be more available or advantageous. This study seeks to randomize patients undergoing patch testing to have patches placed on the back or the thighs. The investigators seek to understand the benefits of testing on the legs versus the back in terms of patient experience as well as achieving a successful test. This study will measure patient experience using a survey administered to patients. Quality of testing will be assessed by study coordinators prior the removal of patches.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Age 18 or older
  • * Undergoing patch testing at Park Nicollet Contact Dermatitis

  • * Both back and thighs adequate for patch testing (see exclusion criteria below)
  • * Patient is 17 or younger
  • * Patient is pregnant or breastfeeding
  • * Specialized patch testing with low number of patches (less than 90)
  • * Rash that would preclude testing on thighs or back
  • * Large tattoos that would preclude testing on thighs or back
  • * Limited space on thighs or back due to body habitus
  • * Patient has specific needs necessitating use of the thighs or back (event, breastfeeding, etc.)
