Breadth, collection, and the habit you keep
At-home blood testing splits into two real categories, and most buyers conflate them. The first is the comprehensive annual panel: a deep, one-or-twice-a-year snapshot of 100 to 160+ markers with AI insights and clinician review. Function Health and Mito Health own this lane. The second is frequent, low-friction check-ins between those deep draws, where a needle-free kit you complete at your kitchen table matters more than raw marker count. That is SiPhox. InsideTracker sits in between, trading breadth for the most explicit do-this-next guidance, and HealthLabs is the à la carte answer when you already know the single test you want.
The longevity-useful signal is the trend, not the single reading. Most markers move on a weeks-to-months timescale, which is why two comprehensive draws a year is the consensus cadence and why a cheap, easy kit for the quarters in between is genuinely valuable. The other honest point: a blood test measures, it does not treat. If a marker comes back off, you still need a clinician to act on it. Buy the test that fits the gap in your stack, then make sure you have a plan for what the numbers tell you.
Want one deep panel done right: Function Health. Want that breadth for less, with past-lab upload: Mito Health. Want explicit food and exercise actions: InsideTracker. Want a true no-needle kit you run often: SiPhox. Want one specific test, fast and cheap: HealthLabs.
Five at-home blood tests worth your money
Function Health - the deepest panel at a fixed price
$365/yr · 160+ lab tests · 2x/year · AI insights + clinician review · Quest network draw
The one we steer most buyers to. Function took the $5,000 executive physical and turned it into a $365/year membership, and made it better: 160+ lab tests run twice a year, plotted as trends instead of one-off numbers, with AI insights flagging what changed and clinician review on anything abnormal. The panel goes deep where primary care stops, covering advanced lipid fractions, hormones, heavy metals, and cancer-relevant screens. The draw is an in-person venous collection at the Quest network, which keeps sample quality controlled. It is a data-and-insight layer, not a prescriber, so pair it with a clinician for anything that needs action. For breadth, cadence, and value in one membership, nothing here beats it.
Mito Health - the same playbook for less, with past-lab upload
$349/yr Core · 100+ biomarkers · Past-lab upload · AI plans + physician consults · HSA/FSA
Mito runs Function's playbook at a lower price: 100+ biomarkers, AI-driven personalized action plans, and physician consultations for $349/year Core. The standout difference is past-lab upload. You can feed in historical bloodwork from your PCP or a prior platform so the AI delivers trends from day one, rather than spending your first year building a baseline. Mito also offers genetics and gut-microbiome add-ons that Function does not, and it is HSA/FSA eligible via Flex, which can make it the cheapest comprehensive panel after tax. The trade is brand maturity: founded in 2023, it trails Function on track record and community. For a first comprehensive panel, it is the rational entry point.
InsideTracker Ultimate - data paired with explicit next steps
$199 Essentials to $589 Ultimate · 48 biomarkers (Ultimate) · DNA add-on $189 · Lab draw or home kit
The original blood-test-plus-AI-advice platform, doing this since 2009 as MIT-spinout science applied to athlete bloodwork. The Ultimate plan tests 48 biomarkers, fewer than Function or Mito, but goes deeper on actionability: every result comes with specific food, exercise, and supplement recommendations tied to your individual numbers, plus DNA-informed adjustments if you add the $189 genomics layer. It also accepts existing lab uploads for free, so you can run the recommendation engine on labs your doctor already ordered. Where Function and Mito tell you what your numbers are, InsideTracker tells you what to do about them. Buy it for the cleaner app and explicit guidance; skip it if you want maximum marker coverage at the lowest cost.
SiPhox Health - the truly at-home, no-needle draw
$99-$189 · Up to 60 biomarkers · At-home EasyDraw, no finger prick · AI action plan · HSA/FSA
The lowest-friction way to actually test as often as longevity tracking wants you to. You collect a small sample at home with the EasyDraw device (upper arm, no finger prick), mail it back, and get results across up to 60 markers in about 7-10 days, with an AI summary and a personalized action plan. It trades the breadth of the 100+ panels for convenience and price: the needle-free collection and an entry price near $99 make quarterly testing realistic, which is where biomarker tracking earns its keep. It is HSA/FSA eligible, and membership plans add recurring testing from about $125. The honest framing: it is testing and insight, not a prescribing relationship. The clean stack is one comprehensive annual panel plus SiPhox for cheaper check-ins between draws.
HealthLabs - a la carte testing without the wait
$24-$459 · Single marker to 100+ panels · Quest + LabCorp · Results in 1-3 days · HSA/FSA
The shortcut when you know the exact test you want and do not want to wait three weeks for a doctor's appointment to order it. Order online, walk into the nearest Quest or LabCorp location, and results land in 1-3 days, faster than the membership platforms because there is no batch processing. Single tests run $24-$69, or assemble your own panel up to comprehensive scope. There is no AI layer, no trend visualization, and no clinician review: you get the raw values and interpret them yourself or share them with your own clinician. For buyers running protocols their PCP will not order for, or anyone comfortable reading their own labs, that is exactly the right trade. It is HSA/FSA eligible and available in most states (not New York).
The one-paragraph answer
For most people, buy Function Health: 160+ lab tests twice a year for $365, with AI insights and clinician review. Want that depth for less, or have old labs to upload? Mito Health runs 100+ biomarkers for $349 and is HSA/FSA eligible. Want explicit food and exercise actions instead of raw data? InsideTracker. Want a genuinely needle-free kit you can run every quarter? SiPhox Health from about $99. Just need one specific marker, fast and cheap? HealthLabs, with results in 1-3 days. For the platform-level view of memberships and concierge tiers, see the best diagnostic platform guide.
A blood test is only worth it if you act on it. Pick the option that fits the gap in your stack, commit to a twice-a-year cadence for the comprehensive panel, and have a clinician relationship ready for anything that comes back off. The cheapest mistake in this category is paying for data you never use.
At-home blood test buyer's questions
What is the best at-home blood test overall?
For most buyers, Function Health: 160+ lab tests run twice a year for $365, with AI-driven insights and clinician review on anything abnormal. It is the deepest panel at the fixed annual price. If you want the same breadth for less, Mito Health runs 100+ biomarkers for $349 and lets you upload past labs. If you want a genuinely needle-free kit you complete at home, SiPhox Health starts around $99.
Function Health vs Mito Health: which one?
Same playbook, different positioning. Function ($365/yr) runs 160+ lab tests twice a year with AI insights and clinician review, and has the longer track record and larger community. Mito ($349/yr Core) runs 100+ biomarkers, lets you upload past bloodwork so the AI works from day one, and offers genetics and gut-microbiome add-ons Function does not. For a first comprehensive panel, Mito is the lower-friction entry. If you are already in Function, do not migrate.
Function vs InsideTracker: which is better?
Function tests far more markers (160+ vs InsideTracker Ultimate at 48) and bundles two draws a year into $365. InsideTracker trades breadth for action: every result comes with specific food, exercise, and supplement recommendations, plus an optional DNA layer ($189). Buy Function for maximum data at a fixed price. Buy InsideTracker if you want explicit do-this guidance and a cleaner app, and you do not want to interpret raw labs yourself.
Is an at-home blood test as accurate as a lab draw?
The analysis is. Every platform here runs samples through CLIA-certified labs, so the assay quality matches a clinic draw. The variable is collection. Function, Mito, InsideTracker, and HealthLabs default to an in-person venous draw at Quest or LabCorp for their comprehensive panels, which keeps collection controlled. SiPhox uses an at-home upper-arm device (no finger prick) that is convenient and reliable for most markers, though venous draw remains the gold standard for a few hormones and lipid fractions.
Do I need a doctor to order an at-home blood test?
No. All five options handle the physician order for you. Function, Mito, InsideTracker, and SiPhox include the requisition in the membership or kit. HealthLabs provides the ordering physician as part of its direct-to-consumer model, so you order online and walk into Quest or LabCorp. Availability varies by state (HealthLabs is not available in New York, for example), so confirm before you buy.
How often should I test my biomarkers?
Twice a year is the consensus cadence for comprehensive panels, which is why Function and Mito build two draws into the annual price. Most markers shift on a weeks-to-months timescale, so monthly testing is wasted spend and annual is too sparse to catch trends. If you are running an aggressive protocol, quarterly is defensible, and a low-friction kit like SiPhox makes that realistic and affordable between your comprehensive draws.
What is the cheapest way to get an at-home blood test?
For a single, specific marker, HealthLabs is the cheapest path, with à la carte tests from about $24 and results in 1-3 days. For an entry-level multi-marker at-home kit, SiPhox starts around $99. For a comprehensive 100+ marker panel, Mito at $349/yr is the lowest credible price, narrowly under Function at $365. Cheapest-per-marker for a deep panel goes to Mito and Function; cheapest single test goes to HealthLabs.
Which at-home blood test is HSA/FSA eligible?
Mito Health, SiPhox Health, and HealthLabs are all HSA/FSA eligible, which effectively discounts them 20-37% pre-tax depending on your bracket. That can make Mito the cheapest comprehensive panel on an after-tax basis and pushes a SiPhox kit well under $99 net. Confirm eligibility with your plan administrator, since some require a medical-necessity step.
Do these blood tests treat anything or prescribe?
No. All five are testing and insight tools, not prescribing relationships. They tell you what your numbers are doing and, in most cases, suggest changes. If a marker comes back abnormal, you still see a clinician to act on it. For active hormone, peptide, or GLP-1 prescriptions, pair your test with a prescribing provider rather than expecting the test to manage treatment.
