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 |
Common Causes of High Anti-dsDNA
Systemic Lupus Erythematosus (SLE) — most specific markerLupus nephritis (elevated anti-dsDNA with low complement = active nephritis)Drug-induced lupus (usually lower titer, less specific pattern)
Common Causes of Low Anti-dsDNA
Anti-dsDNA is negative in approximately 30–40% of confirmed SLE patients — a negative result does not rule out SLE
