Patch Testing

Patch testing involves three appointments in our office, typically:

  • Monday for Patch Application
  • Wednesday for Patch Removal (48 hours later)
  • Thursday or Friday for Patch Reading (72 hours later)

There may be an option of the final patch reading approximately 96 hours later from application versus the standard 72 hours.

Please plan 1.5 hours for the first appointment; subsequent appointments should not exceed 45 minutes.

After your patch reading appointment, if you’ve tested positive to any patch allergens:

You will receive a specific information sheet for each allergen you test positive to (click here for an example)
- electronic copies of these handouts are available in the section below, sorted by panel type
Two “passcodes” will be emailed to you, both necessary to log in to the ACDS CAMP mobile phone application
- the ACDS CAMP app will generate a safe product list (allergen-free) based on your patch reading results
