Folate test cost: $15–$41
By Elo. Last updated September 1, 2026.
A Folate test costs as little as $15 on its own, or $190 in a 100-biomarker bundle. The lowest-cost providers of Folate are Mito Health ($15–$20), DrSays ($24), and Marek Diagnostics ($34). Every price on this page is an all-in total, list price plus whatever draw or physician fee the lab adds at checkout, because the advertised number usually leaves the fee out. Last checked July 2026.
Folate (vitamin B9) is essential for red and white blood cell development and DNA production. Deficiency can cause anemia.

How much does a Folate test cost?
Folate costs $15–$41 on its own, or $190–$689 in a bundle. Those are cash prices, so that's also what Folate costs without insurance.

Cost of Folate in a bundle
Seven packages we track include Folate, and every one of them tests dozens of other markers from the same draw. The cheapest bundle with Folate is Empirical Health's 100-biomarker panel at $190, then Vitals Vault ($199 for 48 markers), Parsley Health ($275 for 41 markers), Mito Health ($315 for 99 markers), Superpower ($349 for 59 markers), InsideTracker ($499 for 48 markers), and LabCorp OnDemand ($689 for 46 markers).
How much does a Folate test cost at Quest Diagnostics?
At Quest Diagnostics, a Folate test costs $71 on its own.
Is a Folate test worth it?
Usually not, in the US. Folic acid has been added to flour and grain products here since 1998, so true deficiency is now uncommon in people who eat a normal diet. Serum folate also bounces around with what you ate this week. It's worth testing in pregnancy, malabsorption, alcohol use disorder, or alongside B12 when someone has unexplained anemia.
Either way, the price shouldn't be what decides it: Mito Health sells Folate for $15 all-in. The cheapest panel that includes it is Empirical Health at $190, which is only worth it if you want the other 99 markers too.
Does insurance cover a Folate test?
Insurance usually covers Folate when a doctor orders it for symptoms or a known condition, though you may still owe a copay or deductible. The in-network negotiated cost is about $15 to $30, against $15 if you pay cash. At a hospital lab the billed charge can reach $120 to $500.
The $22 allowed amount is an estimate, about 1.5x Medicare's $14.70 rate for CPT 82746, and it moves with the lab and the market: the same test is contracted around $18 at one national lab and into the $40s at another. Coinsurance is assumed at 20% once your deductible is met. Your own plan decides both, and most plans apply lab work to the deductible first, so the second outcome above is the one most people land on.
Folate is billed as CPT 82746. That's the code to quote if you call your insurer to ask what you'd owe.
Frequently asked questions about Folate testing
What is the cheapest way to get a Folate test?
The cheapest Folate test is $15–$20 at Mito Health. If you'd rather get more markers out of the same draw, Empirical Health's 100-biomarker panel is $190.
Do I need a doctor's order to get a Folate test?
No. The standalone Folate tests listed above include the physician order in their price, so you can buy online and have your blood drawn without seeing a doctor first. You'd only need your own doctor's order if you want to bill the test to insurance.
How much does a Folate test cost at LabCorp?
LabCorp doesn't publish a flat consumer price for Folate, and what you're charged varies by location. The cheapest way to have Folate drawn at a LabCorp Patient Service Center is through DrSays, a LabCorp-network lab, at $23.98 all-in ($13.99 + $9.99 collection fee).
What is a normal folate level?
A normal serum folate is generally above about 3 to 4 ng/mL, and many labs flag levels below this as deficient. Folate and vitamin B12 are often checked together because their deficiencies overlap.
Do I need to fast for a folate test?
A 6 to 8 hour fast is sometimes requested for a serum folate test because recent meals can raise the level, but practices vary by lab. Avoid folate supplements before testing unless told otherwise.
