What are the 11 signs of lupus?

ANSWER

Your doctor may say you have lupus if you have at least four of 11 signs of the disease that are laid out by experts at the American College of Rheumatology:

  • Butterfly-shaped rash
  • Raised red patches on your skin
  • You're sensitive to light
  • Ulcers in your mouth or nose
  • Arthritis in two or more joints, plus swelling or tenderness
  • Inflammation in the lining of your heart or lungs
  • Seizures or other nerve problems
  • Too much protein in your urine
  • Low blood cell counts
  • Certain antibodies in your blood
  • Results from a blood test called an ANA test that suggest you may have too many "antinuclear" antibodies, which could be a sign of lupus
