ENA (Extractable Nuclear Antigens) Antibody Panel (Labcorp)
This test looks for the presence of several types of autoantibodies in the blood. Autoantibodies are produced when the body's immune system mistakenly attacks its own tissues. There are many types of autoimmune disorders and different types of antibodies are associated with certain disorders. Diagnosing an autoimmune condition can be difficult based just on a person's symptoms because many disorders have similar types of symptoms. Common symptoms include fever, fatigue, swelling or pain in the joints, muscle pain, rash, numbness in the fingers or toes, anemia, sensitivity to light, or depression. Looking for specific types of autoantibodies can help identify which condition a person may have as well as rule out others.
This test includes:
- Anti-nuclear antibody (ANA): A test that looks for the presence of autoantibodies.
- Scleroderma 70 (SCL-70): About 60% of Scleroderma cases will show positive for SCL-70.
- Sjogren Anti-SSA: About 75% of people with Sjogren Syndrome will test positive for SSA. People with Lupus or Scleroderma may also show SSA antibodies.
- Sjorgen Anti-SSB: About 60% of people with Sjogren Syndrome will test positive for SSB. People with Lupus or Scleroderma may also show SSB antibodies.
An ENA test can be ordered when a person has symptoms of an autoimmune disease or as a follow-up to a positive ANA test.
Turnaround for this test is typically 3-5 business days.
