Dual-Specific DNA Antibody Screening Test (Serum/Plasma)

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms suggestive of autoimmune diseases (e.g., joint pain, fatigue, unexplained rashes) or if you’ve been diagnosed with conditions like lupus, rheumatoid arthritis, or other connective tissue disorders. It may also be used as part of a broader evaluation for unexplained inflammatory or immune-related problems.

What to Expect Before the Test

No special preparation is typically needed. You may have a small needle inserted into a vein (usually in your arm) to draw blood. If you’re taking blood pressure medications or have a history of clotting issues, let your provider know beforehand.

What the Test Results Mean

Results are usually qualitative (positive or negative) and indicate whether antibodies were detected. A positive result suggests a potential immune response to DNA, but it doesn’t confirm a specific diagnosis. Follow-up testing or additional evaluation may be needed to explore underlying causes.

Common Reasons for Positive Results

Positive results can occur in autoimmune diseases (e.g., systemic lupus erythematosus), infections, or as a side effect of certain medications. They may also be found incidentally in people without symptoms. Consult your provider to discuss next steps.
