TestWell vs JustLabs
The lowest sticker prices in direct-to-consumer testing, plus $28 in fees on every order. An honest side-by-side comparison covering price, lab partners, test selection, and turnaround.
Pricing data verified October 21, 2026.
The verdict
JustLabs has the lowest sticker prices we track ($5-$9 for common tests) but adds $28 to every order ($18 draw + $10 physician). For a single test, TestWell is cheaper all-in on 62 of the 71 tests both companies sell (TSH $32.99 vs $37). Add a second test and JustLabs usually totals less, because its fees are paid once. Pick TestWell for one test, a Labcorp option, New York or New Jersey, or physician-reviewed guidance with your results; pick JustLabs for a multi-test Quest cart on price alone.

How do prices compare on common tests?
TestWell prices pulled live from our catalog. JustLabs prices verified 2026-10-21. Across the 71 tests both companies sell, TestWell is cheaper all-in on 62 for a single-test order; see the real-order table below for multi-test carts.
All-in columns add each company's per-order fees for a single-test order: TestWell $6 lab processing fee; JustLabs $28.00 ($18 lab draw fee + $10 physician order fee). Fees are charged once per order, so multi-test orders dilute them. Competitor pricing pulled from public ordering pages on 2026-10-21; subject to change.
What does a real order cost?
Fees are paid once per order, so the cheaper company depends on how many tests are in the cart. Totals below include every fee each company charges.

TestWell totals are live catalog prices plus the single $6 lab processing fee. JustLabs totals are their sticker or panel price on 2026-10-21 plus $28 in per-order fees. New York and New Jersey orders at TestWell use BioReference pricing, which differs for some items.
Where does TestWell win?
- •One flat $6 fee per order versus $28 ($18 draw + $10 physician) — TestWell is cheaper all-in on 62 of the 71 matched single-test orders (checked 2026-10-21)
- •The price you see is the price you pay: no fee appears at checkout that wasn't on the test page
- •Choice of Quest or Labcorp at checkout, plus New York and New Jersey through BioReference — JustLabs is Quest-only and cannot serve NY/NJ
- •Every reference range, guide and test page carries a named physician reviewer with a public license; JustLabs' 220+ blog posts are published as 'Justlabs Editorial' with no named clinician
- •Verified patient reviews with star ratings on the test pages and a public reviews page; JustLabs shows hand-picked testimonials with no rating, count or verification trail
- •Every test page states what can throw its result off — medications, supplements, fasting, time of day — from one physician-reviewed registry, and our AI-results prompt reads your report against those same reviewed ranges; JustLabs covers this one blog post at a time
- •60+ curated panels with the real biomarker count shown (CMP = 14, CBC = 15), so 'a 4-test panel' isn't mistaken for 4 numbers
- •180+ individual tests including Labcorp-only assays (Vitamin D 1,25-dihydroxy, ApoE, Factor V Leiden, MTHFR); JustLabs lists 83 Quest tests
Where does JustLabs win?
- •Multi-test à-la-carte orders: from two individually priced tests up, JustLabs usually totals less because its $28 in fees is paid once (TSH + Vitamin D is $62 there vs $74.98 here). TestWell's curated panels close that gap — the General Wellness Panel (the same four tests as their Basic Wellness Panel) is $55.99 all-in vs their $58
- •Eight single tests are cheaper at JustLabs even after fees, mostly specialty assays where their sticker is far below ours: heavy metals panel, Omega-3 Index, LH, prolactin, thyroid antibodies, PSA free & total, and by about a dollar CoQ10 and folate
- •Faster quoted turnaround (1-2 business days) on many routine tests
- •Bilingual: every test and panel page is mirrored in Spanish
We’d rather be honest about where they have an edge — pick the tool that matches your situation.
Is JustLabs legit?
Yes. JustLabs is a real direct-to-consumer lab-ordering service: you pay online, a physician in their network authorizes the order, and your blood is drawn at a Quest Diagnostics patient service center — the same CLIA-certified Quest lab that runs TestWell's Quest orders, so the assays and reference ranges are identical. Their site discloses the two per-order fees ($18 lab draw + $10 physician order) on the homepage and at checkout, and FSA/HSA cards are accepted.
The things to know before ordering are structural, not red flags: sticker prices exclude $28 in fees, so a $9 test costs $37; Quest is the only lab, which rules out New York and New Jersey and any town where Labcorp is the closer draw site; and their educational content is published as 'Justlabs Editorial' rather than under a named, licensed clinician. If none of those matter for your order, it is a legitimate way to buy Quest tests cheaply — especially several at once.
JustLabs alternatives
TestWell — one $6 fee per order instead of $28, Quest or Labcorp at checkout, BioReference in New York and New Jersey, and every test page and reference range reviewed by a named physician. Cheapest all-in for a single test on 62 of the 70 tests both companies sell; not the cheapest for a large Quest-only cart.
Quest Health (questhealth.com) — Quest's own storefront. Same lab as JustLabs with no separate draw fee, but sticker prices run 4-5× higher (TSH $49, A1c $39, Vitamin D $75); see our Quest Health comparison.
Labcorp OnDemand — the equivalent from Labcorp, for people whose nearest draw site is a Labcorp; prices sit between Quest Health and TestWell. Ulta Lab Tests and Walk-In Lab also sell both Quest and Labcorp tests à la carte, with their own fee structures — compared on our other pages.
When is TestWell not the right choice?
Every service here has real limits, including ours. Skip TestWell — and consider JustLabs or another option — if any of these apply to you.
- You're ordering two or more individually priced tests in one Quest draw and none of TestWell's curated panels covers your list — JustLabs' $28 in fees is paid once, so à-la-carte carts of two or more favor them.
- You want Spanish-language test pages; TestWell's Spanish mirror is still rolling out.
- You want a clinician consult included. A licensed physician authorizes every TestWell order, but that review is not a visit — there is no call to walk through results unless you bring them to your own provider.
- You can't get to a draw site. TestWell is venous-draw only at Quest, Labcorp and BioReference locations; we don't ship at-home finger-prick kits.

Frequently asked questions
Are TestWell and JustLabs using the same labs?
When the lab partner is the same (Quest or Labcorp), the actual analysis is identical — same machines, same reference ranges, same CLIA-certified facility. The differences are price, ordering experience, and what's included.
Can I switch from JustLabs to TestWell mid-year?
Yes. Lab tests aren't subscriptions you have to cancel — each order stands alone. If you've already paid for a year of JustLabs, use what you've paid for, and order any additional tests through TestWell.
Will my doctor accept TestWell results?
Yes. Your results are CLIA-certified lab results from Quest or Labcorp — the same labs your doctor uses. You can download a PDF and bring it to any provider.
What does a JustLabs order actually cost?
The sticker price of each test plus $28 in fees per order: an $18 lab draw fee and a $10 physician order fee, both disclosed on their homepage and at checkout. A $9 TSH test is $37 all-in; at TestWell the same test is $26.99 plus a single $6 fee, $32.99 all-in. Fees are per order, so adding tests to a JustLabs cart brings the average down quickly.
Is JustLabs cheaper than TestWell?
For one test, usually not — once both companies' fees are included, TestWell is cheaper all-in on 62 of the 71 tests both sell (checked 2026-10-21). From two tests up, JustLabs is usually cheaper because its $28 in fees is spread across the order: TSH plus Vitamin D is $62 there versus $74.98 here. Compare the all-in total for your specific list, not the stickers.
Is JustLabs legit?
Yes — orders are physician-authorized and drawn at Quest Diagnostics patient service centers, the same CLIA-certified lab TestWell uses for Quest orders, and their $18 draw and $10 physician fees are disclosed before you pay. The trade-offs are structural: $28 in fees on every order, Quest only (no New York or New Jersey), and content published without a named clinician.
What are the best alternatives to JustLabs?
TestWell for single tests, Labcorp, New York/New Jersey and physician-reviewed results pages; Quest Health for buying directly from Quest at higher sticker prices; Labcorp OnDemand for Labcorp-only areas; Ulta Lab Tests or Walk-In Lab for another à-la-carte menu across both labs. For a large Quest-only cart, JustLabs itself is often the cheapest total.
Does JustLabs serve New York or New Jersey?
Not as of our check: JustLabs orders are drawn at Quest Diagnostics only, and Quest does not accept self-ordered tests in New York or New Jersey. TestWell routes those states to BioReference Laboratories automatically.
Are JustLabs and TestWell using the same lab?
Often, yes. Both send Quest orders to the same Quest patient service centers, so the assay and the reference ranges are identical for those tests. TestWell also offers Labcorp at checkout and BioReference in NY/NJ.
