WHAT IS PATCH TESTING?
Patch testing is a simple procedure to help diagnose allergic contact dermatitis and identify the causative agent(s). This involves the application of a series of purified ingredients to your back in small amounts as test patches.
For more information on patch testing visit dermnetnz.org
We test using an extended battery of allergens.
PRIOR TO YOUR APPOINTMENT:
If your back is hairy please shave or wax one or two days before patch testing.
Do NOT take cortisone (prednisolone 10mg or less a day is usually okay) tablets before or during patch testing, without checking with the doctor.
Do NOT use creams (including topical corticosteroids / ‘cortisone’ creams) or powders on your back the day the patches are applied.
FOR YOUR FIRST APPOINTMENT:
AFTER THE TEST
If you are shown to be allergic to any of the substances tested, you will be given comprehensive information and advice on how to avoid this allergen. If you have any problems or concerns please contact the clinic or surgery.
