Vitamin D is one of the most commonly requested lab tests in the country and one of the easiest to buy at the wrong price. The same 25-hydroxy measurement costs $19 on a prepaid marketplace, $59 at a discount lab reseller, $75 at Quest, $99 at Labcorp OnDemand, and $99 in a finger-prick kit that ships to your door. Medicare pays $29.60 for it.
There is also a second, pricier vitamin D test that shares the name and answers a different question, and a whole shelf of wellness panels that quietly fold vitamin D in at three to five times the standalone price. This guide sorts out which test is which, what each route costs as of August 2026, and where the retesting math starts to matter. For the wider lab menu and how direct ordering works in general, see our blood work cost guide.
What Does a Vitamin D Test Cost Without Insurance?
All figures below come from each seller’s own published page plus the CY 2026 Q3 release of the CMS Clinical Laboratory Fee Schedule, checked in August 2026.
| How you buy it | Low | Typical | High |
|---|---|---|---|
| Medicare benchmark, 25-hydroxy (CPT 82306, 2026 CLFS) | $29.60 | $29.60 | $29.60 |
| Prepaid lab marketplace (MDsave) | $19 | $66 | $276 |
| Direct-to-consumer lab, 25-hydroxy alone | $59 (Walk-in Lab, plus $6 fee) | $75 (Quest, plus $6 fee) | $99 (Labcorp OnDemand) |
| At-home finger-prick kit | $99 (Everlywell, 25-OH D plus hs-CRP) | $99 | $99 |
| Wellness panel that includes vitamin D | $126.75 (Labcorp Vitamin Deficiency Test on sale) | $169 list | $329 to $399 (Quest Comprehensive and Elite profiles) |
| 1,25-dihydroxy (calcitriol) test, CPT 82652 | $38.50 (Medicare) | $85 (Walk-in Lab, plus $6 fee) | $85 |
Two numbers on the marketplace row are worth separating. MDsave lists $19 to $276 as the national spread and $66 as its own prepaid national average, against an “estimated national average” charge of $132. That $132 figure is roughly what gets billed when nobody negotiates, and the $66 is what the same providers accept when the price is posted in advance. Sources disagree on what “typical” means here by a factor of two, which is exactly why the range is published rather than a single number.
Walk-in Lab also sells a branded QuestAssureD 25-Hydroxyvitamin D (D2, D3) test at $95 plus the $6 physician fee, which measures total vitamin D broken out into its two forms. It is the same nutrient, reported in more detail, at $36 more than the plain version.
What Drives the Price
Which vitamin D test the order specifies
There are two. The standard one is 25-hydroxyvitamin D, CPT 82306, and it is what almost every order means by “a vitamin D test.” The NIH Office of Dietary Supplements states plainly that serum 25(OH)D is the main indicator of vitamin D status. The other is 1,25-dihydroxyvitamin D (calcitriol), CPT 82652, which NIH ODS describes as generally not a good indicator of status because it has a half-life measured in hours and is tightly regulated by parathyroid hormone. It is a specialist’s test, not a screening one.
The price gap follows. Medicare pays $38.50 for the 1,25-dihydroxy test versus $29.60 for 25-hydroxy, about 30% more. Walk-in Lab charges $85 versus $59 for the same pair, about 44% more. Both sources point the same direction, and both matter for the same practical reason: if you are buying from a menu, check the code you are actually purchasing.
Standalone test vs. bundled panel
This is the largest multiplier in the table. Quest’s Women’s Basic Health Profile is $199 plus the $6 fee and does not include vitamin D at all; the Comprehensive tier that adds it is $329, and the Elite profile with 85-plus markers is $399. Labcorp OnDemand’s Vitamin Deficiency Test (vitamin D, B12, and folate) lists at $169 and was on sale at $126.75 as of August 2026. Against a $75 standalone Quest test, every one of those is a bundle premium. Bundles are only cheap per marker, never cheap per answer.
Who draws the blood
Direct-to-consumer prices are flat and posted. A vitamin D drawn as part of a doctor-ordered panel goes wherever the practice sends it, and if that is a hospital-affiliated outpatient lab, the charge is set by the hospital’s list price rather than a lab menu. You will not see the number until the bill arrives. Taking the paper order to a standalone Quest or Labcorp draw site instead is usually allowed and usually cheaper.
Convenience, packaged as a kit
Everlywell sells a Vitamin D & Inflammation Test for $99: a finger-prick blood-spot kit that measures 25-OH D and high-sensitivity CRP, with free shipping and HSA/FSA acceptance. That is above the $59 to $75 you would pay to walk into a lab for the vitamin D number alone, and the extra marker is not the reason. You are buying the not-going-anywhere.
Assay variability, which is a retesting cost
NIH ODS notes that measuring 25(OH)D is complicated by considerable variability between available assays, and that a result can read falsely low or falsely high depending on the assay and the laboratory. The consumer consequence is financial: if you retest, running the follow-up at the same lab on the same method keeps the two numbers comparable, and paying twice for results you cannot line up is the most avoidable expense in this whole category.
Cash Price vs. Insurance
Vitamin D is a diagnostic test, not a preventive screening covered in full under the ACA, so it usually lands against your deductible. Under a high-deductible plan that means you pay the negotiated rate in full, and that rate is often higher than the $59 to $99 you can buy the test for outright. Medicare’s own $29.60 rate is a reminder of what the assay costs to run, and how much of everything above it is storefront.
Payers also apply coverage rules to vitamin D testing more aggressively than to a basic metabolic panel, and a denied claim leaves you paying list price rather than the cash price you could have chosen up front. If you are uninsured or pre-deductible, buying direct removes that risk entirely: the price is fixed, disclosed, and HSA/FSA eligible at Quest, Labcorp OnDemand, Walk-in Lab, and Everlywell.
The trade-off is the same as with any direct-order lab. The result is yours to share, but it does not automatically appear in a provider’s chart, and a clinician managing something specific may want it re-run through their own lab. Ask before you pay twice.
How to Pay Less
- Buy the standalone 25-hydroxy test, not a panel. $59 at Walk-in Lab plus a $6 fee, or $75 plus $6 at Quest, versus $169 to $399 for panels that include it. If vitamin D is the only number you came for, the bundle is pure markup.
- Check a prepaid marketplace before you accept a quote. MDsave publishes a $19 to $276 national range with a $66 prepaid average for the Vitamin (D3) 25-Hydroxy, against a $132 estimated national average charge. Anything quoted near the top of that spread deserves a second look, and our fair price checker makes the comparison quick.
- Take a doctor’s lab order to a standalone draw site. If a clinic hands you a requisition, you can generally choose where to have it drawn. Standalone labs charge menu prices; hospital outpatient labs charge list prices, which are posted in their price transparency files if you want to see the difference before you go.
- Use a sliding-scale clinic when you need the visit too. Federally funded health centers and free clinics price the appointment and basic labs together on an income-based scale, which beats paying for a visit and a test separately. Our guide to free clinics and sliding-scale care covers how to find one near you.
- Skip the kit unless you genuinely cannot get to a lab. Everlywell’s $99 finger-prick test is convenient, not cheap. Two lab draws cost about what one kit does.
- Dispute a lab bill that looks nothing like these numbers. A vitamin D line item billed at several hundred dollars is a list price, not a cost. Request an itemized statement and use our walkthrough on negotiating medical bills; single lab line items are among the easiest charges to get reduced.
Bottom Line
The test you almost certainly want is 25-hydroxyvitamin D, CPT 82306, and its honest 2026 self-pay price is $59 to $99 buying direct, or as low as $19 on a prepaid marketplace. Medicare pays $29.60, which is the closest thing to a cost benchmark you will find. The 1,25-dihydroxy version costs 30% to 44% more depending on whose price list you read, and it is not the screening test.
Everything above $100 is a package: a wellness panel, a shipped kit, or a hospital lab’s list price. Decide which of those you are actually buying before you hand over a card.
