At-Home Blood Test Kits Compared (2026): Accuracy, Lab, Price
At-home blood test kits compared: which lab runs each, how the sample is taken, how many markers, the yearly cost, and how accurate finger-prick results are.

Comparison
Below: each kit, who runs it, how the sample is taken, and what the research says about accuracy. If you want a broad panel, a lab draw is cheaper per marker; see our cost per measured biomarker chart. Every option is ranked on the best blood tests page.
The kits, side by side
| Kit | Price | Sample | Markers measured | Lab |
|---|---|---|---|---|
| SiPhox Longevity Essentials | $298 a year, testing every 6 months | Upper-arm device | 22 | Accredited partner lab, not named |
| SiPhox Ultimate 360 | $548 a year, every 6 months | Upper-arm device | 42 | Same |
| Rythm | $948 a year, monthly | Upper-arm device (Tasso+) | 23 | Its own lab |
| LetsGetChecked Male Hormone Complete | $199 | Finger prick plus saliva | 5 | Its own lab |
| LetsGetChecked Diabetes and Heart | $99 | Finger prick | 5 | Its own lab |
| Everlywell Women's Health Test | $249 | Finger prick plus saliva | 10 | Not named |
| Maximus At-Home Testosterone | $99.99 | Upper-arm device | Not itemised | Not named |
| myLAB Box Women's Health | $259 | Finger prick and saliva | Not itemised | Not named |
Kit prices are one kit unless the row says otherwise. SiPhox's yearly figure is two cycles at its listed price plus its 25-dollar shipping each time, our arithmetic; testing more often costs more. Rythm's is twelve monthly tests before shipping and tax, which it does not publish.
Who runs the sample
A kit is only as good as the lab behind it. The ones that say so:
- Rythm: "The sample is then tested in Rythm's own CLIA-certified, CAP-accredited laboratory using FDA-regulated analyzers" (Rythm FAQ).
- SiPhox: its FAQ says it works only with CLIA-certified, CAP-accredited partner labs (SiPhox FAQ), but it does not name the lab.
- LetsGetChecked runs kits at its own lab in California, which it describes as CLIA-approved and CAP-accredited.
- Everlywell and myLAB Box say their partner labs are CLIA-certified without naming them.
You can look up any US lab by name or ZIP code on the CMS QCOR CLIA lookup. CLIA shows the lab meets federal quality standards; it does not show that a test is useful for you.

How accurate are at-home kits?
It depends on the marker and the method. A finger prick gives a few drops of capillary blood, which can differ from blood drawn from a vein. A 2015 Rice University study found large drop-to-drop variation in finger-prick measures of hemoglobin, white cells and platelets, and needed several drops pooled to match a venous draw (Fierce Biotech). HbA1c and many lipid tests hold up better on small samples.
Upper-arm devices collect more blood than a finger prick. The Tasso+ device got FDA 510(k) clearance as a capillary blood collection device in 2022 (Business Wire). Clearance covers the collection device, not every test a lab runs on the sample; the lab has to validate each one.
Saliva tests measure something different from blood. Everlywell's men's kit measures DHEA in saliva, not DHEA-S in blood, so its results are not comparable with a lab panel. If a home result surprises you, repeat it with a venous draw before acting on it, and talk to a clinician.
Kit or lab draw?
| You want | Better choice | Why |
|---|---|---|
| A broad yearly panel | Lab draw | More markers, cheaper per marker |
| One focused question, such as testosterone or A1c | Kit or a single lab test | Compare the kit with a single test at a lab store |
| To track a few markers often | Subscription kit | Monthly or quarterly at home |
| To avoid a lab visit entirely | Kit, or a membership with at-home draw | Some memberships send a phlebotomist for a fee |
State limits

Questions
FAQ
Are at-home blood tests accurate?
For some markers, close to a lab draw; for others, less so. Finger-prick blood counts vary from drop to drop. Choose a kit that names a CLIA-certified lab and repeat any surprising result at a lab.
What is the cheapest at-home blood test?
A single-purpose kit such as LetsGetChecked's Diabetes and Heart test at $99. Per marker, home kits cost more than a lab panel.
Which at-home kit tests the most markers?
SiPhox Ultimate 360, with 42 measured markers by our count.
Does an at-home kit need a doctor's order?
SiPhox says its tests need no referral. Other kits include a clinician review of the order or results.
Do at-home kits work in New York?
Some do not: SiPhox does not serve New York, and LetsGetChecked bars several hormone kits there.
Can I use HSA or FSA money for a kit?
SiPhox, Rythm, Everlywell, LetsGetChecked and myLAB Box all say they accept HSA or FSA cards.
