Quick answer: If you want the widest, doctor-reviewed snapshot of your health in one sitting, a full-panel lab membership wins on data per dollar. Superpower (about $199 a year for 100+ biomarkers, reviewed by a care team) is the best all-around value, and it draws blood at a Quest lab near you. Function Health covers a similar 100+ test panel twice a year for around $365 and leans more clinical. If you only need one or two specific markers checked, a per-kit option like Everlywell is simpler and cheaper up front. SiPhox Health is the pick when a needle is the thing stopping you, because it now collects blood from your upper arm at home with no separate lab visit. Whichever you choose, treat the results as the start of a conversation with a clinician, not a diagnosis.

Who should test their biomarkers at home
At-home and direct-to-consumer lab testing earns its keep when you want numbers more than once a year and you do not want to wait for a physical to get them. A few concrete situations where it pays off:
- You changed something and want proof it worked. You cut added sugar, started zone-2 cardio, or began a statin, and you want to see fasting insulin, triglycerides, or ApoB actually move in 8 to 12 weeks. An annual physical cannot show you that arc.
- You have a family history that keeps you up at night. Early heart disease, type 2 diabetes, or thyroid disease in close relatives means markers like Lp(a), HbA1c, and TSH are worth watching years before symptoms show.
- Your doctor will only order the basics. A standard insurance panel often stops at total cholesterol, glucose, and a metabolic panel. It rarely includes ApoB, fasting insulin, hs-CRP, or Lp(a), which are some of the markers that tell you the most about long-term risk.
- You are optimizing, not sick. You feel fine and want a baseline to defend, plus a way to catch a slow drift (creeping fasting glucose, falling vitamin D, rising ferritin) while it is still easy to reverse.
- You hate needles or live far from a lab. A self-collected kit or an at-home arm draw removes the two biggest reasons people skip testing entirely.
Who should not rely on at-home testing alone: anyone with active symptoms (chest pain, unexplained weight loss, severe fatigue), anyone managing a diagnosed condition where dosing depends on labs, and anyone who would act on a result without confirming it. In those cases, see a clinician and get a clinician-ordered test. At-home testing is for tracking and early signal, not for diagnosis or treatment decisions.
How we compared them
We did not rank on sticker price, because a cheap single test can cost more per useful insight than a full panel. We weighed five things that actually change the experience and the value:
- Breadth of the panel. How many biomarkers you get, and whether they include the ones that matter (ApoB, fasting insulin, hs-CRP, Lp(a)) rather than just the standard cholesterol-and-glucose set.
- Who reviews the results. Whether a clinician or care team looks at your numbers and tells you what to do next, or whether you are handed a PDF and left to interpret it.
- How the sample is collected. Venous draw at a lab, a self-collected kit mailed back, or an at-home arm-based draw. This drives both convenience and which markers are reliable.
- Lab certification. Whether the analysis runs through a CLIA-certified (and ideally CAP-accredited) lab, which is the bar for clinical-grade results.
- Tracking over time. Whether the service trends your markers across tests so you can see direction, not just a single snapshot.
The four services compared
Superpower: best overall value for a full-body picture
Superpower is a yearly membership built around a broad lab panel with care-team review and a dashboard that trends your markers test over test. For roughly $199 a year (higher in New York and New Jersey, around $399, because of state lab regulations) you get a full blood draw covering 100+ biomarkers across heart, metabolic, hormonal, inflammatory, nutrient, liver, and kidney health, plus a report that rolls the results into health scores and a plain-language action plan.
What you get: 100+ biomarkers at the start of your membership year, a structured report, a personalized action plan, and access to a care team you can message. Supplements and follow-up testing are offered through the membership.
Lab certification: Samples are processed through certified clinical labs, with the blood draw done at Quest Diagnostics locations.
Collection method: A standard venous blood draw at one of 3,000+ Quest sites, which is included. If you would rather not travel, a mobile phlebotomist can come to your home or office for an extra fee (around $119).
Best for: Someone who wants the widest snapshot for the lowest annual price and plans to retest and track trends.
Limitations: It is a venous draw, so you do need to get to a lab (or pay for the mobile option). Pricing is materially higher in NY and NJ. The membership renews annually, so factor that into the cost, not just year one.
Price: About $199 a year (around $399 in NY and NJ). HSA and FSA eligible.
Full-body lab membership: 100+ biomarkers, doctor-reviewed, tracked over time.
Function Health: best for a structured, deeply clinical annual deep-dive
Function Health covers a comparable 100+ biomarker panel (the company markets 160+ lab tests across the year once add-ons and the mid-year retest are counted) with clinician review on every result. The model is built around testing roughly twice a year: a large baseline panel, then a follow-up partway through the year to see what changed.
What you get: 100+ lab tests at baseline across every major organ system, a mid-year retest of a subset of markers, clinician-reviewed results, and an action plan with food and supplement guidance. Add-on tests are available on demand.
Lab certification: Samples are processed at Quest Diagnostics labs by licensed technicians, which meet clinical-grade standards.
Collection method: Venous blood draw at a partner lab location.
Best for: Someone who prefers a structured once-or-twice-a-year clinical deep dive with clinician oversight, rather than frequent self-directed retesting.
Limitations: Like Superpower, it requires a lab visit for the draw. Pricing has shifted over time, so check the current rate before you sign up. The cadence is set around two tests a year, which is less flexible if you want to retest a single marker on a short timeline.
Price: Around $365 a year at standard pricing (multi-year promotions sometimes lower the effective annual cost). HSA and FSA eligible.
100+ lab tests twice a year with clinician insights and a tracking dashboard.
Everlywell: best for single, targeted tests you can do from home
Everlywell is not a membership, it is a catalog of individual at-home kits. You buy the one you need (thyroid, metabolic, vitamin D, women’s or men’s hormones, food sensitivity, and more), collect the sample yourself, mail it back, and get results online, often with the option of a telehealth follow-up.
What you get: One focused kit per purchase, digital results, and optional virtual care visits. Pricing typically runs from about $49 for a basic panel up to roughly $249 for a comprehensive hormone collection.
Lab certification: Tests are processed in CLIA-certified labs, and some are also CAP-accredited.
Collection method: Self-collected at home, depending on the test, by dried blood spot (finger-prick onto a card), saliva, or urine. For panels that need a full draw, Everlywell also offers in-person collection through Quest.
Best for: Someone who already knows the one or two markers they want to check and does not need a 100-marker dashboard.
Limitations: Buying several single kits adds up fast and can cost more than a full-panel membership while giving you less. Self-collected dried blood spot and saliva are convenient but, for a few markers, less precise than a venous draw, so confirm anything borderline with a lab test.
Price: About $49 to $249 per kit. HSA and FSA eligible.
At-home test kits for specific markers (metabolic, thyroid, hormones) shipped to your door.
SiPhox Health: best for testing at home without a clinic visit
SiPhox Health is the answer to the most common objection to testing: getting to a lab. In the US it now uses an upper-arm collection device called EasyDraw that you apply at home in a few minutes, with no separate phlebotomist appointment. Earlier versions leaned on finger-prick collection, so if you read an older review describing SiPhox as a finger-prick service, that is out of date for the current US program.
What you get: Panels you can personalize, from a focused heart-and-metabolic set up to an Ultimate 360 panel measuring up to 60 biomarkers across cardiovascular, metabolic, hormonal, thyroid, liver, kidney, inflammation, and nutritional health. Results come with analysis, supplement suggestions, and an action plan, and you can test monthly, quarterly, or every six months.
Lab certification: Samples are processed in a CLIA-certified lab.
Collection method: At-home upper-arm collection (EasyDraw) in the US, with no needles and no clinic trip. This is the standout feature.
Best for: Someone who wants to test entirely from home and values convenience and a flexible cadence over the absolute widest panel.
Limitations: The base membership covers fewer markers than the full Superpower or Function panels, so reaching 60 markers means the Ultimate 360 upgrade. Turnaround is typically about 5 to 10 days. At-home self-collection, while validated, is still worth confirming with a venous draw for any result that would drive a medication change.
Price: Around $125 for the base membership, about $225 with the Ultimate 360 upgrade. HSA and FSA eligible.

What biomarkers actually matter, and why
A panel is only as useful as the markers in it and your ability to read them. Here is what the high-value ones tell you, in plain language. None of this is a substitute for a clinician interpreting your full picture.
Lipids and cardiovascular risk
- ApoB counts the actual number of artery-clogging particles in your blood. Many cardiologists consider it a better predictor of heart risk than LDL cholesterol alone. Higher is worse, and it is one of the markers a standard insurance panel usually skips.
- LDL cholesterol is the classic “bad” cholesterol. Elevated LDL over years drives plaque buildup. Lower is generally better, especially if you already have risk factors.
- HDL cholesterol is the “good” cholesterol that helps clear cholesterol from arteries. Very low HDL is a risk flag, though chasing a very high number is not the goal.
- Triglycerides are blood fats that rise with excess sugar, refined carbs, and alcohol. High triglycerides often travel with insulin resistance.
- Lp(a) is a largely genetic, lifelong risk marker. You usually only need to measure it once. A high Lp(a) means you should be more aggressive about every other cardiovascular lever, because you cannot move Lp(a) much with lifestyle.
Metabolic health
- Fasting glucose is your blood sugar after not eating. Creeping into the prediabetic range is an early warning, years before a diabetes diagnosis.
- Fasting insulin often rises before glucose does. It is one of the earliest signs of insulin resistance, and another marker standard panels rarely include.
- HbA1c reflects your average blood sugar over roughly the past three months, so it smooths out day-to-day noise. It is the standard marker for screening and tracking diabetes risk.
Inflammation
- hs-CRP (high-sensitivity C-reactive protein) measures low-grade, chronic inflammation linked to cardiovascular and metabolic risk. A short-term spike can just mean you are fighting a cold, so a single high reading is best rechecked rather than acted on immediately.
Thyroid
- TSH is the first-line thyroid screen. High TSH can suggest an underactive thyroid (fatigue, weight gain, cold sensitivity), low TSH an overactive one.
- Free T4 and Free T3 are the actual thyroid hormones. They help interpret a borderline TSH and clarify what your thyroid is really doing.
Hormones, vitamins, and stores
- Sex hormones (testosterone, estradiol, and related markers) matter for energy, libido, mood, and body composition, and they shift with age. Interpretation is very individual, so pair these with a clinician.
- Vitamin D is widely low, especially in winter and for people who spend little time in the sun. Low vitamin D affects bone, immune, and mood health, and it is one of the easiest deficiencies to correct.
- Ferritin reflects your iron stores. Low ferritin can cause fatigue and hair loss (common in menstruating women and endurance athletes), while high ferritin can signal inflammation or iron overload.
- Homocysteine is an amino acid that, when elevated, is associated with cardiovascular risk and can reflect low B-vitamin status (B12, folate, B6).
How to read your results
The single most useful thing to understand is the difference between a reference range and an optimal range.
A reference range is the statistical band that covers most of the population the lab tested. Being “in range” means you are not an outlier, not that you are healthy. Some reference ranges are wide enough that you can sit at the unhealthy edge of “normal” for years. An optimal range is a tighter target some clinicians aim for based on the lowest-risk outcomes, and it is often narrower than the lab’s reference band. Different services and doctors define optimal differently, which is exactly why a result should prompt a conversation, not a self-prescribed change.
A few practical rules:
- Direction beats a single dot. One value is a snapshot. Three values over a year show a trend, and trends are where the real signal lives. This is the main argument for memberships that track over time.
- Recheck surprises before you react. A single off result can come from a non-fasting sample, a recent illness, hard exercise the day before, or normal lab variation. Confirm anything alarming with a repeat test, ideally a clinician-ordered venous draw.
- See a doctor promptly for red flags. Markedly high glucose or HbA1c, a very high ApoB or LDL with other risk factors, severe anemia, or any result paired with real symptoms should go to a clinician, not into a wait-and-see folder.
At-home kit vs lab draw vs your doctor’s order
These three routes are not interchangeable. Each has an honest tradeoff.
At-home self-collection (Everlywell dried blood spot or saliva, SiPhox EasyDraw) wins on convenience and removes the needle-and-clinic barrier. The collection methods used by reputable services are clinically validated, but for a handful of markers a self-collected sample is slightly less precise than a venous draw, and collection technique (a too-small blood spot, for example) can affect results. It is excellent for tracking, less ideal as the final word for a diagnosis.
Venous lab draw (Superpower, Function, or any in-person Quest collection) is the clinical gold standard for most markers. It costs a trip to a lab but gives the most reliable numbers and supports the widest panels, including markers that are hard to do well from a finger-prick.
Your own doctor’s order is the right path whenever a result will change treatment, when you have symptoms, or when insurance might cover a standard panel more cheaply than paying out of pocket. A clinician-ordered test also lands directly in your medical record and comes with built-in interpretation.
When at-home is not appropriate: active symptoms that need a diagnosis, monitoring a condition where medication dosing depends on the labs, pregnancy-related testing, or any situation where you would act on a result without professional confirmation. In those cases, start with a clinician.
How much it costs
Rough 2026 pricing, so you can compare per-insight value rather than just the sticker:
- Superpower: about $199 a year for 100+ biomarkers (around $399 in NY and NJ). Works out to a low cost per marker if you use the full panel and retest.
- Function Health: around $365 a year at standard pricing for a 100+ test panel plus a mid-year retest. Multi-year promotions can lower the effective annual cost.
- Everlywell: about $49 to $249 per individual kit. Cheapest entry point for one marker, but buying several kits can exceed the cost of a full membership.
- SiPhox Health: around $125 for the base membership, about $225 for the Ultimate 360 (up to 60 biomarkers), with at-home collection included.
All four are typically HSA and FSA eligible, which effectively discounts them by your tax rate. None are usually covered by insurance, because they are ordered directly by you rather than through your provider. If you only need a standard panel and have insurance, asking your own doctor to order it can be the cheapest route of all.
Frequently asked questions
Are at-home biomarker tests accurate?
Reputable services process samples in CLIA-certified labs, and some are also CAP-accredited, so the analysis itself is clinical grade. The variable is collection. A venous draw (Superpower, Function, or an in-person Quest visit) is the gold standard. Self-collected methods like dried blood spot, saliva, and at-home arm draws are clinically validated and reliable for tracking, but collection technique and timing can affect a few markers. For any diagnosis or medication decision, confirm with a clinician-ordered test.
Can I pay with my FSA or HSA?
Generally yes. Superpower, Function Health, Everlywell, and SiPhox all describe their tests as HSA and FSA eligible. That effectively reduces the cost by your marginal tax rate. Keep the receipt, and check your plan administrator’s rules, since some require an itemized receipt or a letter of medical necessity.
Do I need to fast before testing?
For accurate lipids (especially triglycerides), glucose, and insulin, most providers recommend fasting for 8 to 12 hours, with water allowed. Many other markers do not require fasting. Follow the specific instructions your provider sends, and try to test under consistent conditions each time (same time of day, similar fasting state) so your trends are comparable.
How often should I test?
For general tracking, once or twice a year is typical, which is why the membership models are built around that cadence. Retest sooner, around 8 to 12 weeks, when you have changed your diet, training, or a medication and want to see the effect on a specific marker. Markers like Lp(a) are largely genetic and usually only need to be measured once.
Are these services legit?
Yes. The services covered here run samples through certified clinical labs and, in the case of the membership models, have clinicians or care teams review results. The honest caveat is that direct-to-consumer testing is designed for screening and tracking, not for diagnosing or treating disease on its own. Used that way, they are legitimate and useful.
Do I need a doctor to order the test?
No. These are direct-to-consumer services, so you order them yourself. Many include a physician order behind the scenes to authorize the lab work, and the membership services add clinician review of your results. You do not, however, get a long-term treating doctor out of the deal, so loop in your own clinician for anything that needs ongoing management.
Which service gives the most data for the money?
For breadth per dollar, the full-panel memberships lead. Superpower covers 100+ biomarkers for around $199 a year, which is hard to beat on a per-marker basis if you use the whole panel. Function Health covers a comparable panel with a clinical lean and a built-in mid-year retest. If you only want one or two markers, a single Everlywell kit is cheaper up front, but it gives you far less.
What if I’m afraid of needles or can’t get to a lab?
This is exactly where SiPhox Health and Everlywell shine. SiPhox now uses an at-home upper-arm EasyDraw device in the US with no clinic visit and no finger-prick. Everlywell uses self-collected dried blood spot, saliva, or urine depending on the test. Superpower also offers a mobile phlebotomist who comes to you for an added fee if you would rather not travel to a Quest location.
Will at-home results go to my doctor?
Not automatically. You will get a digital report you can download and share, but unlike a clinician-ordered test, the results do not land in your medical record on their own. If you want them in your chart, bring the report to your next appointment and ask your provider to add it.
Can these tests replace my annual physical?
No. They cover more biomarkers than a typical physical, but a physical also includes a physical exam, blood pressure, history, and a clinician’s judgment about your whole picture. Think of at-home testing as a powerful complement that gives you data between visits, not a replacement for primary care.
