Anti-dsDNA antibodies (ANA follow-up marker)
Anti ds-DNA + ss-DNA tests detect antibodies against double-stranded and single-stranded DNA. Anti-dsDNA is highly specific for systemic lupus erythematosus (SLE) and its levels often correlate with disease activity, particularly lupus nephritis. Anti-ssDNA is less specific but may be present in drug-induced lupus.
Turnaround 48 hours, estimate Turnaround: up to 48 hours after your blood draw (estimate).
Anti ds-DNA + ss-DNA: what this test measures
This test measures antibodies directed against both double-stranded and single-stranded DNA. Anti-dsDNA is the more clinically significant component and is included in SLE classification criteria.
Anti ds-DNA + ss-DNA: why this value matters
Anti-dsDNA is one of the most specific markers for SLE and is included in the ACR/EULAR classification criteria. Rising titres may predict lupus flares, especially renal involvement.
Anti ds-DNA + ss-DNA: how the blood test works
- Referral
- No GP referral needed. After the order we arrange the referral through ZorgDomein, within one business day; orders after 17:00 or at the weekend start on the next business day. ZorgDomein emails a barcode, and that barcode is what the draw site needs.
- The draw
- A blood draw from a vein in the arm, at a partner laboratory's draw site. No home kit, no finger prick.
- Results
- Turnaround: up to 48 hours after your blood draw (estimate).
- Where
- 650+ draw sites run by independent laboratories across the Netherlands. Draw sites
Anti ds-DNA + ss-DNA: when is testing worthwhile?
Testing could be indicated when SLE is suspected, for monitoring known SLE disease activity, or when ANA is positive and further characterisation is needed.
Anti ds-DNA + ss-DNA: symptoms of a high or low value
Low Levels
A negative result makes SLE less likely but does not exclude it. Some SLE patients are anti-dsDNA negative, particularly those with mild or cutaneous-predominant disease.
High Levels
Elevated anti-dsDNA in the context of compatible symptoms strongly supports SLE diagnosis. High titres are particularly associated with lupus nephritis and may fluctuate with disease activity.
Anti ds-DNA + ss-DNA: lifestyle and this value
If anti-dsDNA positive, consult a rheumatologist. Sun protection is essential as UV exposure can trigger lupus flares. Maintain regular monitoring of kidney function and disease activity markers.
Anti ds-DNA + ss-DNA: frequently asked questions
How specific is anti-dsDNA for lupus?
Anti-dsDNA has approximately 95% specificity for SLE, making it one of the most useful confirmatory tests when lupus is suspected.
Do anti-dsDNA levels correlate with disease activity?
Often yes, particularly for renal involvement. Rising titres may precede clinical flares, making it useful for monitoring.
What is the difference between dsDNA and ssDNA antibodies?
Anti-dsDNA is highly specific for SLE. Anti-ssDNA is less specific and can be found in drug-induced lupus and other autoimmune conditions.
