Anti-dsDNA Antibodies Normal Ranges
Anti-double-stranded DNA (anti-dsDNA) antibodies are highly specific for Systemic Lupus Erythematosus (SLE/Lupus).
| Reference Range | Unit | Notes |
|---|---|---|
| 0 – 30 | IU/mL | Negative <30; Positive ≥30 |
Why Doctors Order the Anti-dsDNA Antibodies Test
Anti-dsDNA is positive in approximately 60–70% of SLE patients and is present in fewer than 1% of healthy individuals — making it highly specific for lupus. It is included in both the ACR and EULAR SLE classification criteria as a high-weight criterion.

What a Low or High Anti-dsDNA Can Be Associated With
Below the reference range
- Anti-dsDNA is negative in approximately 30–40% of confirmed SLE patients — a negative result does not rule out SLE
Above the reference range
- Systemic Lupus Erythematosus (SLE) — most specific marker
- Lupus nephritis (elevated anti-dsDNA with low complement = active nephritis)
- Drug-induced lupus (usually lower titer, less specific pattern)
- Rare: mixed connective tissue disease, Sjögren's syndrome
These are common associations, not a diagnosis. A single result is read alongside your symptoms, history and other tests — discuss it with your doctor.
What Can Change Your Anti-dsDNA Result
Before you read too much into a result, consider whether any of these applied:
- Active infection (can cause transient low-titer anti-dsDNA in some assays)
- Assay method differences — ELISA is more sensitive; Crithidia luciliae immunofluorescence is more specific
- Some medications (especially minocycline, TNF inhibitors) can induce anti-dsDNA
Preparing for the test: No fasting required. Anti-dsDNA is most useful when SLE is suspected after a positive ANA test.
Symptoms That Often Prompt Anti-dsDNA Testing
- Butterfly rash (malar rash) across the face
- Kidney involvement: foamy urine (proteinuria), hypertension, reduced kidney function
- Joint pain and swelling (polyarthritis)
- Fatigue, fever, and hair loss
- Serositis: pleurisy (pleuritic chest pain), pericarditis
