Anti-Nuclear Antibody (ANA) Profile (Serum) - Qualitative Immunoassay

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like joint pain, fatigue, rash, or unexplained fever. It’s also used as part of a broader evaluation for autoimmune diseases, especially when other tests or symptoms suggest these conditions.

What to Expect During the Test

You’ll have a small needle inserted into your arm to draw blood. The process takes about 5 minutes. The lab will analyze a sample of your serum using an immunoassay method to detect specific antibodies. Results are typically available within a few days.

What the Results Mean

A positive result means your blood contains antibodies against nuclear components of cells, which can signal an autoimmune condition. However, a positive result doesn’t always mean you have a specific disease. Follow-up tests and evaluations are usually needed to determine the exact cause.

Common Conditions Linked to Positive Results

Positive ANA results are common in autoimmune diseases such as systemic lupus erythematosus (SLE), scleroderma, mixed connective tissue disease, and rheumatoid arthritis. However, some people without autoimmune diseases can also test positive, so additional testing is often required to narrow down the diagnosis.
