Folate test cost — $4.80–$26.95
Folate · measured in ng/mL
Repletion lowers homocysteine — prefer food/methylfolate.
Higher is betterReference range
An assay-specific reference interval has not yet been added to this guide.
Use the interval printed beside this exact result, including its specimen, units, age/sex group and collection conditions. A range for a similarly named test may not apply.
Optimal range / clinical target
PeptideLab has not verified a separate ‘optimal’ target for this measurement. Reference intervals, diagnostic cutoffs and treatment targets answer different questions.

Does insurance cover Folate testing?
When a clinician orders Folate for a diagnosis or to follow a known condition, most plans cover it — and many cover routine screening as $0 preventive care for eligible adults. The catch is you need a qualifying reason and an in-network order; a “I just want to see my number” request often isn’t covered, and if you haven’t met your deductible you can end up paying the lab’s full list price anyway.
The direct-pay prices above skip insurance entirely: you pay the cash price, test on your own schedule with no doctor visit, and it’s HSA/FSA-eligible. For a single marker that’s often cheaper — and faster — than a copay plus deductible exposure.
Folate inside a bundle
Every compared membership/panel that includes Folate, cheapest first. Worth it when you want several markers at once rather than a single test.

What Folate is
Vitamin B9 — essential for one-carbon metabolism, DNA synthesis, and homocysteine remethylation. RBC folate reflects longer-term stores than serum folate.
Why it matters for longevity & performance
Adequate folate (with B12/B6) lowers homocysteine, a vascular and cognitive risk factor; excess unmetabolized folic acid is debated, so food and methylfolate sources are favored.
Folate testing — frequently asked
Do I need to fast for a Folate test?
No. Folate does not require fasting — you can test any time of day.
Do I need a doctor's order to get a Folate test?
No. Direct-to-consumer labs (GoodLabs, Ulta, Quest and Labcorp OnDemand) include the physician order in the price — you order online and visit a draw site, no appointment with your own doctor needed.
How fast are Folate results?
Usually 1–3 business days after your blood draw; most results post to the lab's online portal.
What's the difference between the standard and optimal Folate range?
Reference intervals describe results in a reference population; they do not by themselves diagnose or exclude disease. A treatment target depends on the condition and the person. PeptideLab has not verified a separate ‘optimal’ target for this measurement. Reference intervals, diagnostic cutoffs and treatment targets answer different questions.
Does insurance cover Folate testing?
Often, when ordered for a diagnosis; many plans cover it as preventive care at no cost for eligible adults. The direct-pay prices above let you skip insurance and test on your own schedule.
