Transdermal allergy testing

Allergy is one of the world's most common chronic conditions. The state of the art method for allergy testing is the skin prick test (SPT) where different allergens are introduced into the skin of the tested person. This method is at best semi- quantitative, a relatively low number of tests can be performed and patients might experience unpleasant reactions. This invention is a novel allergy test providing fast, accurate and quantitative monitoring of allergic reactions in the skin. As a novelty, microneedle-based electrochemical sensor arrays are used to introduce allergens in the skin and perform electrochemical detection of biomarkers released from activated mast cells in the interstitial fluid.
