The verdict, up front

After testing all 13, the service that best lived up to its marketing was Superpower. Its claim of 100-plus biomarkers in one comprehensive blood panel checked out, and the physician-guided results were the clearest we saw, all for a membership at $199 per year, or $179 with code MASON20.[1] Hundred Health and Everlywell followed as strong picks for different needs.

The traditional lab networks (Quest and Labcorp) were the most clinically accurate for raw numbers, but they offered almost no interpretation.[14] Below we break down what each service claims, and what we found.

How we fact-checked each service

Over the past year our team ordered lab tests online from every health testing service below, completed the bloodwork, then checked each marketing claim against the result and against published clinical standards for biomarker testing.[2] We scored on six weighted criteria:

Biomarker depth

How many, and which, biomarkers each panel actually covers, from basic metabolic to advanced cardiovascular, hormonal and longevity markers.[6]

Lab accuracy

Whether samples are processed in CLIA-certified, CAP-accredited labs, and how results compared to a clinician-ordered baseline panel.[1][14]

Physician oversight

The level of licensed-physician review and follow-up, which direct-to-consumer services are legally required to include.[3]

Cost and transparency

Sticker price, what is included, hidden fees, and whether HSA or FSA payment is accepted.[16]

Experience and speed

Sign-up, sample collection (finger-stick, kit or in-person draw), app quality and turnaround time to results.

Data privacy

How your health data is stored, whether it is sold or shared, and how easily you can delete it.[4]

#2 · Best for Physician-Led Longevity

Hundred Health

Best for people who want a doctor in the loop on every result
4.6
out of 5
★★★★★
VerifiedThe claim: "A dedicated physician reviews every panel." What we found: A licensed physician reviewed our results and built a personalized protocol, consistent with endocrine and preventive guidance.[13]
70+ biomarkers Membership pricing Dedicated physician Longevity focus

Hundred Health leans hardest into clinical guidance. Its comprehensive panels are paired with a dedicated physician who reviews your results, builds a personalized protocol and follows up, closer to a modern longevity clinic than a test kit. In testing, the depth of the consult and the personalization of recommendations were standouts.

It is an excellent fit if you value the human, physician-led relationship over a self-serve app, and want testing tied directly to an evolving health plan.

What we liked
  • Dedicated physician reviews every panel
  • Personalized, longevity-oriented protocols
  • Strong follow-up and accountability
Keep in mind
  • Membership model, not a one-time kit
  • Fewer raw biomarkers than Superpower
  • Premium positioning

Our verdict: the most concierge-doctor experience here, ideal if guidance matters more to you than sheer biomarker count.

#3 · Best At-Home Convenience

Everlywell

Best for affordable, targeted at-home tests
4.4
out of 5
★★★★☆
Mostly accurateThe claim: "Lab-certified results from home." What we found: True. Samples go to CLIA-certified labs and results are physician-reviewed, though finger-stick collection occasionally needs a careful retake.[1]
From ~$49 30+ test kits CLIA-certified labs Physician-reviewed HSA/FSA eligible

Everlywell is the most accessible name in at-home testing, with 30-plus targeted kits covering thyroid, metabolic, vitamin D, food sensitivity, sexual health and more. You collect a finger-stick sample at home, mail it to a CLIA-certified lab, and get physician-reviewed results in a clean app within days.[6] Pricing starts around $49, and HSA or FSA is accepted.[16]

It is not a 100-biomarker deep dive, but for answering a specific question affordably and quickly, it was the easiest service to recommend to most people.

What we liked
  • Affordable, with frequent bundle discounts
  • Huge range of targeted test kits
  • Simple finger-stick collection at home
  • HSA and FSA accepted
Keep in mind
  • Single-topic kits, not one full-body panel
  • Finger-stick samples can require a careful retake
  • Less hand-holding than membership services

Our verdict: the best entry point to blood testing, affordable, convenient and reliable for targeted questions.

The recommendations were the most sports-oriented of any service we tested, and the goal tracking was genuinely useful.

What we liked
  • Clear, prioritized recommendations
  • Strong fit for athletes
  • Optional fitness-tracker integration
Keep in mind

#7 · Best Affordable At-Home Comprehensive Panel

SiPhox Health

Best for a broad at-home comprehensive blood panel on a budget
4.1
out of 5
★★★★☆
Mostly accurateThe claim: "Lab-quality results from a finger-stick at home." What we found: Largely true. The mail-in sample is processed in CLIA-certified labs, though a finger-stick is less foolproof than a venous draw.[1]
50+ biomarkersFrom ~$95At-home finger-stickCLIA-certified labs

SiPhox Health delivers a surprisingly broad comprehensive blood panel from a mail-in, at-home sample, covering metabolic, heart, hormone and thyroid markers at a fraction of a clinic price. For people who want wide coverage without a membership, it was the best value in the at-home category.

What we liked
  • Broad panel for the price
  • Fully at-home collection
  • Clean results dashboard
Keep in mind
  • Finger-stick can need a careful retake
  • Less guidance than membership services

Our verdict: the best-value at-home comprehensive panel we tested.

#8 · Best Established Lab Network

Quest Health

Best for trusted, in-person lab draws nationwide
4.1
out of 5
★★★★☆
VerifiedThe claim: "Doctor-trusted lab results." What we found: True. Quest runs full venous draws in CLIA-certified, CAP-accredited labs, the same network many physicians use.[14][15]
From ~$592,000+ locationsVenous drawPhysician-ordered

Quest Health lets you order lab tests online and complete a true venous blood draw at one of Quest's thousands of patient service centers. Because it is a full venous sample rather than a finger-stick, accuracy is excellent and the test menu is broad.

What we liked
  • Gold-standard venous draws
  • Huge nationwide footprint
  • Trusted, long-established lab
Keep in mind
  • Requires an in-person appointment
  • Results portal is more clinical than friendly
  • Minimal interpretation or guidance

Our verdict: the most clinically trusted self-order option, if you do not mind visiting a lab.

#9 · Best Nationwide Access

Labcorp OnDemand

Best for self-ordered tests at a major lab chain
4.0
out of 5
★★★★☆
VerifiedThe claim: "Order your own labs, nationwide." What we found: True. A physician authorizes the order and you complete a venous draw at a Labcorp site.[3]
From ~$592,000+ sitesVenous drawFSA/HSA

Labcorp OnDemand is Quest's closest analog. Order online, get a physician's authorization, and complete a venous draw at a Labcorp location. The test catalog is deep and the lab is one of the most established in the country.

What we liked
  • Reliable venous draws nationwide
  • Broad, well-priced test menu
  • FSA and HSA accepted
Keep in mind
  • In-person visit required
  • Limited results guidance
  • Booking can be clunky in some areas

Our verdict: a dependable, no-frills way to get accurate labs at scale.

#10 · Best for Gut and Cellular Health Testing

Viome

Best if you want microbiome and RNA insights alongside blood markers
3.9
out of 5
★★★★☆
MixedThe claim: "Full-body intelligence from RNA testing." What we found: The gut and cellular RNA analysis is genuinely novel, but it is not a substitute for a standard comprehensive blood panel, and some recommendations outpace the published evidence.[5]
From ~$199RNA + blood markersAt-home kitFood and supplement plan

Viome stands apart by focusing on RNA sequencing of the gut, oral and cellular environment, with some blood biomarkers layered in. The output is a detailed food and supplement plan. It is the most innovative service here, but it answers a different question than a traditional blood panel, so treat it as a complement rather than a replacement.

What we liked
  • Unique microbiome and RNA insights
  • Detailed personalized food plan
  • Fully at-home collection
Keep in mind
  • Not a standard blood panel
  • Strong push toward its own supplements
  • Some claims run ahead of the evidence

Our verdict: fascinating for gut and cellular health, but pair it with real bloodwork.

#11 · Best for Confidential Testing

LetsGetChecked

Best for private at-home testing with nurse support
3.8
out of 5
★★★★☆
VerifiedThe claim: "Nurse support for your results." What we found: True. A nursing team was available to walk through results, in line with recommended patient follow-up.[7]
From ~$89At-home kitsNurse support lineDiscreet packaging

LetsGetChecked offers a tidy menu of at-home kits covering wellness, hormones, sexual health and more, with discreet packaging and a nursing team available to walk you through positive results. Collection is straightforward and results arrive in a clear portal within a few days.

What we liked
  • Discreet, confidential experience
  • Nurse support for results
  • Clean, easy-to-read portal
Keep in mind
  • Pricier than Everlywell for similar panels
  • Smaller catalog than the lab networks

Our verdict: a strong, private at-home option, especially for sensitive tests you would rather handle quietly.

myLAB Box

Best for discreet at-home STI and wellness screening
3.9
out of 5
★★★★☆
Mostly accurateThe claim: "Free telehealth consult on positives." What we found: Accurate for its STI panels, though the wellness catalog is narrower than advertised.[9]
From ~$79At-home kitsTelehealth consultFast turnaround

myLAB Box specializes in at-home sexual health and wellness screening, with discreet kits and a free telehealth consult if you test positive. It is a focused, judgment-free option for STI panels and a handful of wellness markers.

What we liked
  • Strong sexual-health catalog
  • Telehealth consult on positives
  • Fully at-home and discreet
Keep in mind
  • Narrower scope outside sexual health
  • Higher per-test cost

Our verdict: the go-to for private, at-home sexual health testing.

#13 · Best for A La Carte Ordering

Personalabs

Best for picking individual tests on a budget
3.8
out of 5
★★★★☆
MixedThe claim: "Affordable tests from $29." What we found: The entry price is real, but costs climb quickly once you add several individual tests.[16]
From ~$29Order single testsLab drawPhysician-ordered

Personalabs is built for people who know exactly which test they want. You can order individual labs a la carte at low prices, then complete a draw at a partner lab. There is little guidance, but the flexibility and price per test are hard to beat.

What we liked
  • Lowest entry price of the group
  • Order exactly the tests you want
  • Large individual-test catalog
Keep in mind
  • Bare-bones interface and guidance
  • Costs add up if you order many tests

Our verdict: best for the informed, budget-minded self-orderer.

How to choose the right blood testing service

Ordering lab tests online has never been easier, but the best health testing service depends on what you are trying to learn. Start with your goal, then match it to the format:

1. Define your goal first

2. Finger-stick versus venous draw

At-home finger-stick samples are convenient and fine for most markers, but a venous draw (the standard tube at a lab) is the gold standard for accuracy and is needed for some tests.[1] Membership services like Superpower send a phlebotomist to you, giving you venous-draw accuracy without the lab trip.

3. Look for real physician oversight

Every legitimate direct-to-consumer service includes a physician order.[3] The difference is what happens after results: a PDF you interpret alone, or a clinician who explains the numbers and tells you what to do next.

4. Check the lab and the privacy policy

Confirm samples go to a CLIA-certified, CAP-accredited lab, and read how your data is stored and whether it can be sold.[2][4] The services ranked highest here scored well on both.

Who should get comprehensive blood work?

Generally healthy adults benefit from an annual baseline panel to catch issues early.[7] If you are managing a condition, optimizing performance, or over 40, more frequent and more comprehensive testing (the kind Superpower and Hundred Health provide) gives you trend data that a one-off snapshot cannot.[11]

Frequently asked questions

Are at-home blood tests accurate?
Reputable services process samples in the same CLIA-certified, CAP-accredited labs your doctor uses.[1] Accuracy mostly comes down to correct sample collection. Follow the kit instructions, and choose a venous-draw or mobile-phlebotomy option when the highest accuracy matters.
How much do blood testing services cost?
Single at-home tests start around $49, comprehensive panels run roughly $100 to $500, and full membership programs with physician guidance like Superpower start around $199 per year, and Superpower takes $20 off with code MASON20. Many services accept HSA and FSA.[16]
Do I need a doctor's order?
No. Direct-to-consumer services include a physician order with your purchase.[3] A licensed physician authorizes the panel and reviews your results behind the scenes, so you can order tests yourself.
Can I use HSA or FSA funds?
Most services here, including Everlywell and Superpower, accept HSA and FSA cards for eligible diagnostic tests.[16] Check at checkout for your specific test.
How often should I get comprehensive blood work?
For healthy adults focused on prevention, an annual comprehensive panel is a sensible baseline.[7] People managing a condition or optimizing performance may test every 3 to 6 months. Always interpret results with a clinician.
