I am the mother of a 10 year old girl. She has developed red patches on her skin all over the body for the last 4 days. The doctor has advised a patch skin test. Could you please explain what this test is, what it indicates, and how long it usually takes?
Answered by 1 Apollo Doctors
A patch test is used to find out if your childs red skin patches are due to an allergic skin reaction. It involves placing tiny amounts of common allergens on the skin (usually the back) using patches, which are left in place for 48 hours. After that, the doctor will check the skin for any reaction. This test helps identify what substances your child may be allergic to, such as soaps, metals, or fabrics.

My serum IgE level is 4653 IU/mL. I have a history of allergies, asthma, and psoriasis since childhood, and I also get frequent fungal infections. What tests can be done, or how can we diagnose whether I have Autosomal Recessive Hyper IgE Syndrome (AR HIES)?
