PATCH TESTING
LEARN WHAT IS CAUSING YOUR RASH
When an allergic patient comes into contact with an allergen they are sensitive to, they will develop an itchy eczema like rash that can appear anywhere from 2 days to 2 weeks later. This delayed onset makes identifying the causative agent of contact dermatitis very challenging based on history alone. In patch testing, small aliquots of potential allergens are applied to the skin of the back to replicate a localized allergic contact reaction. At the final reading, allergens that result in eczema are identified and instructions on avoidance are provided. Patch tests differ from skin prick tests, which are used to diagnose systemic allergy and are of limited use in dermatitis.
