ANA Titer
ANA titer reports the highest dilution of serum at which antinuclear antibodies are still detectable and quantifies the strength of a positive ANA. Higher titers (for example 1:320 or greater) are more likely to reflect true autoimmune disease, while low titers (1:40 to 1:80) can occur in healthy people. Titer is interpreted alongside pattern and specific autoantibodies.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for ANA Titer. How we verify ranges.
- No stated targetNo separate optimal establishedA titer below the lab's negative cutoff is expected; a positive titer is a prompt for follow-up, not a value to optimize
- Lab reference intervalNegative: <1:40, Positive: ≥1:80What a lab report flags against. A lab interval is not an optimal target.

Why ANA Titer matters
Quantifies ANA concentration. Higher titers more strongly associated with autoimmune disease. Pattern and titer guide further testing.
Which Providers Test ANA Titer?
Function Health is both the cheapest ($365/year) and the most comprehensive (160+ biomarkers) panel that includes ANA Titer.
3 panels that include it, cheapest first
| Provider | Annual Cost | Total Biomarkers | $/Biomarker |
|---|---|---|---|
 Function Health | $365 | 160+ | $2.28 |
| $365 | 100+ | $3.65 | |
| $499 | 100+ | $4.99 |
$/Biomarker is annual cost divided by the panel's advertised biomarker count, not the price of this one test. We track 23 blood test providers (32 plans); 21 of those plans are itemized marker by marker. Compare all of them.

Frequently Asked Questions
What is the optimal range for ANA Titer?
No separate optimal established: A titer below the lab's negative cutoff is expected; a positive titer is a prompt for follow-up, not a value to optimize. Lab reference interval: Negative: <1:40, Positive: ≥1:80. That is what a lab report flags against, not an optimal target.
Which blood test providers include ANA Titer?
3 of the 21 blood testing panels we itemize marker by marker include ANA Titer in their panels. This biomarker has limited availability.
