Allergy Prick Skin Test for Eczema Diagnosis

A minute portion of the alleged allergen is placed on an area of skin, more than likely the person’s back, and then the skin is softly pierced with a small needle. It is the sign of definite allergic reaction to the allergen in question, if the patient develops redness and a bump where they have been pierced.

After a short passage of time for eczema diagnosis, each one of the skin test reactions is then gauged for two elements- redness and inflammation. The test is said to be a “positive skin test”, if a big enough skin reaction is considered. This indicates that there may be the presence of the allergy at the site of the testing. The patient’s list of symptoms and the outcome of the allergy prick test are compared by the doctor. Generally, this test takes about thirty to forty minutes to complete.
