Rythm Health Review (2026): The Real Yearly Cost of a $79 Test

Rythm sells one thing: an upper-arm blood kit that arrives every 30 days, runs a fixed panel of hormones, heart, thyroid and metabolic markers, and shows results in an app. Below: the yearly arithmetic, what the panel covers and misses, who runs it, the refund and privacy terms, and how it compares with SiPhox and the lab memberships. Our full scorecard is on the Rythm review page, and every service is ranked on the best blood tests page.

What Rythm costs per year

The price on the page is per test. The membership "will renew every 30 days" (Rythm FAQ), so the default is 12 kits a year. Members can skip, and Rythm says "you can skip up to three months at a time" (Rythm FAQ). That turns one product into several yearly prices:

The first kit carries a discount, and Rythm does not publish the shipping amount, so the true yearly bill is a little higher than our figures. Per kit, Rythm is reasonable for an at-home panel. Per year at the default cadence it costs more than a broad lab membership that measures four times as many markers once or twice.

What the panel measures, and what it skips

Rythm advertises 25+ biomarkers. We count 23 measured markers after setting aside calculated values such as the LDL to ApoB ratio. The panel includes total and free testosterone, estradiol, SHBG, cortisol, TSH, ApoB, LDL and HDL cholesterol and hs-CRP. Free T3, free T4 and progesterone are on the women's panel only.

What it leaves out matters if you want a full yearly picture. There is no Lp(a), no CBC, no full metabolic panel and no ferritin-plus-iron set, and it reports fructosamine rather than HbA1c for blood sugar. Our coverage table shows the gaps plan by plan, and ApoB and Lp(a) each have their own page. Rythm is built for watching a small set of markers move month to month, not for one broad check.

Who runs the test

Rythm runs its own lab, which is unusual for a kit company. Its FAQ says the sample "is then tested in Rythm’s own CLIA-certified, CAP-accredited laboratory using FDA-regulated analyzers" (Rythm FAQ). Collection uses an upper-arm device: "Rythm uses an FDA-cleared blood collection device, Tasso+" (Rythm FAQ). The clearance covers the collection device; each marker still has to be validated by the lab for that sample type.

On review, Rythm says "All Rythm results are reviewed and signed off by a state licensed physician before being made available to you" (Rythm FAQ). That is a lab sign-off, not a consult. Its consent form says the services "do not create a physician-patient relationship" (Rythm consent), so nobody at Rythm advises you on a result. You can check the lab yourself on the CMS QCOR CLIA lookup; Rythm says to search for "Rythm Health" and pick Nebraska in the CAP directory.

How accurate is an at-home sample?

An upper-arm device draws more blood than a single finger drop, which helps. The classic warning comes from a Rice University study of finger-prick blood, which concluded: "These data suggest caution when using measurements from a single drop of fingerprick blood." (Am J Clin Pathol, 2015). Rythm's own FAQ notes results "can be affected by factors such as collection technique" (Rythm FAQ). If a result surprises you, repeat it with a venous draw at a lab before acting on it. Our at-home kits guide compares every kit on this point.

Refunds, cancelling and states

Cancelling is simple: the subscription stops from your dashboard, with no fee. The refund terms are narrow: Rythm's money-back offer applies "for first-time purchases only" (Rythm FAQ). You must finish the test and ask within seven days of your results.

Rythm sells everywhere in the US: "Rythm is currently available nationwide across all 50 U.S. states." (Rythm FAQ). That includes New York, where SiPhox does not sell. See Rythm in our state matrix.

On payment, "Rythm is HSA/FSA eligible" (Rythm FAQ). Our HSA and FSA guide lists every provider's wording.

Privacy

Rythm's footer reads "HIPAA Aligned", which is not the same as being a covered entity. Its privacy policy says "We may also use deidentified information and results for health research purposes" (Rythm privacy policy), and that it may disclose personal information "to law enforcement, government authorities, and private parties" in good faith for compliance and protection (Rythm privacy policy). We found no statement that it sells health data. Our blood test privacy guide puts this wording next to every other provider's.

Our verdict

Rythm is a good at-home kit with a lab it owns and the widest state coverage of any kit we track. Its weakness is the yearly bill at the monthly default. Buy it if you will act on a monthly trend in hormones or ApoB; otherwise set the skip to the maximum, or compare a twice-yearly kit at SiPhox and the lab memberships on our cost page.
