How are hives diagnosed?

Dr. Mehmet Oz, MD
Cardiology (Cardiovascular Disease)
Hives are diagnosed by a physician through visual inspection and interviews. In the interviews, the doctor will seek to understand what food and/or medication has been taken, past history of allergies or hives, and how long the condition has persisted.
Hives are diagnosed based on their appearance. Your doctor may ask questions to find out if something is causing an allergic reaction. Occasionally, your doctor may suggest a skin or blood test to identify specific allergies. If the hives are chronic (lasting more than 6 weeks) it may be difficult to pin down the cause. In this case the doctor may perform other tests to try to find the cause of the hives, which could include infection, cancer, autoimmune disease, thyroid disorders, or stress. Make sure to let the doctor know about any other symptoms you may be experiencing.
