Skin tests are generally considered a safe and accurate method of allergy testing. However, tests are conducted in your allergist’s office to make sure that you receive adequate medical supervision in case of a more severe reaction. In rare cases, people develop systemic responses to an allergy test. Notify your doctor right away if the following occur:
● Difficulty breathing
● Large rash
● Swelling of the mouth or face
● Trouble swallowing
After the skin testing appointment, your doctor will remove any markings from your skin and clean the area with rubbing alcohol. You may be prescribed a topical cream such as cortisone to reduce the itching and redness. If your testing includes a patch test, you won’t be able to get the affected area wet for a period of time. Your doctor will tell you what activities to avoid, such as swimming and baths, until your next appointment.
