These are important results to discuss with a rheumatologist, as interpreting them requires looking at the full clinical picture — not just the numbers alone.

These are important results to discuss with a rheumatologist, as interpreting them requires looking at the full clinical picture — not just the numbers alone.
Here's what's generally known about these two results:
ANA at 1:40
- Most labs consider a positive ANA to be at a ratio of 1:80 or higher
- A result of 1:40 is considered low and may fall below the threshold for a positive result
- However, different labs have different cutoff points, so it's worth confirming with your doctor
Anti-dsDNA at 33.0
- This test is more specific to lupus than the ANA test
- Whether 33.0 is considered positive depends entirely on the reference range used by the lab that processed your test
- High anti-dsDNA levels are often associated with active lupus, particularly when kidneys may be involved On their own, these two results cannot confirm or rule out either form of lupus. A diagnosis also takes into account:
- Your physical symptoms
- Other blood and urine tests
- Your medical history
- Possibly skin or kidney biopsies
A rheumatologist is really the right person to piece all of this together. Bringing your lab report with the reference ranges included will help make that conversation much more productive.
