Patch testing procedure │Contact Dermatitis │ Contact allergy

Patch tests are used in patients with dermatitis, to find out whether their skin condition may be caused or aggravated by a contact allergy. Patch tests are not the same as skin prick tests, which are used to diagnose hay fever allergy (house dust mite, grass pollens and cat dander). Skin prick tests have very limited value for patients with skin rashes.
Patch testing consists of 20 Allergens which includes Vaseline as control.
