Why This Test Is Done

Your doctor may order this test if you have symptoms like unexplained fatigue, joint pain, or blood clotting issues. It can also be part of evaluating conditions like lupus or other autoimmune diseases.

What to Expect Before the Test

No special preparation is needed. Bring any medications or questions to your appointment. Blood is drawn from a vein, usually in your arm.

What the Test Results Mean

Common Conditions Linked to Positive Results

Elevated levels may be associated with autoimmune disorders like systemic lupus erythematosus (SLE), antiphospholipid syndrome, or other connective tissue diseases.

Clinical interpretation
