Atopy patch tests may identify patients at risk for systemic contact dermatitis

ConclusionOur aggregate findings suggest that most APTs, but not dust mite, behave like conventional patch tests to low ‐potency allergens. They are more likely to be positive in patients with chronically inflamed skin and to identify allergens that cause SCD. The higher prevalence of APT positivity to foods in young children is consistent with food allergy as a trigger of AD (also known as SCD) being more common i n children than adults. Positive APTs define patients who may have SCD; negative APTs may guide elimination diets.
