Allergy Patch Testing

What to Expect

To complete the allergy patch testing, you will need to be scheduled for patch test application, scheduled two days later for patch test removal and initial reading of results, and two to three days after that for final reading of results.

On your initial visit, the patch test, which contains several chambers of antigens, will be applied to your back, and tape will be placed to keep it in place. Do not shower or get your back wet for the first 48 hours. Upon return two days later, the tape and chambers will be removed, and the initial reading will be done. You can shower and get your back wet with water once the chambers have been removed, but do not rub your back with soap or any other product.

You will return another two to three days for the final reading. Your physician will discuss with you any relevant positive response and a treatment plan will be reviewed.

Important Information

  • Do not shower or get your back wet for the first 48 hours.
  • Do not exercise or participate in any activity that may cause excessive sweating.
  • Do not take oral steroids during the testing period, unless directed to by your physician.
  • Discontinue topical medication on the back for two weeks prior to the patch test.
  • Do not tan or use a tanning bed within four days prior to the patch.
