How Do You Find Out If You Have Lupus?

Answer:

No single test can show that you have lupus. Your doctor may have to run several tests and study your medical history. It may take time for the doctor to diagnose lupus.

Telling a doctor about your symptoms and other problems you have had can help him or her understand your situation. Your history can provide clues to your disease.

The doctor will look for rashes and other signs that something is wrong.

Blood and urine may be done and samples often show if your immune system is overactive.

A biopsy, tissue that is removed by a minor surgical procedure, may be examined under a microscope. Skin or kidney tissue examined in this way can show signs of an autoimmune disease.
