Best for

Cortisol, Inflammatory Markers

Standout strength

Includes named biomarkers across multiple wellness domains, with longitudinal trends and derived insights.

Important watch-out

Inclusions differ by sex. Hematocrit and hemoglobin are male-only; free T3, free T4 and progesterone are female-only. The combined list also includes derived insights, so it is not a count of biomarkers measured for every customer.

The Test Grade. The Reason Behind It.

Strong overall documentation and usefulness, with limitations worth comparing before purchase.

A lower grade does not mean a panel is a bad personal fit. Your Fit Score can be higher when its purpose, price, sample, access, or support matches what you need.

Important limits and omissions

  • Performing laboratory identity, assay methods, and analytical performance details require confirmation for this panel.
  • Shipping and tax are added to the $79 regular monthly price, and the exact final checkout total varies by order.
  • The exact performing laboratory facility for an order is not named; Rythm states it owns and operates a laboratory and may use third-party accredited laboratories as needed.
  • No per-offer assay methods or numerical analytical performance are published; the lab page claims assay validation against reference methods and an accuracy guarantee without figures.
  • Rythm does not guarantee results for every biomarker on a panel, may withhold or remove biomarker results, and may add, modify, suspend, or discontinue any biomarker or panel offering at any time.
  • Turnaround times vary with no fixed commitment; the only published timing is results in under 48 hours (48 business hours after a timely return).
  • The 30-day money-back guarantee is first-purchase only, requires a completed test, and the request must be within 7 days of receiving results; used kits are not eligible for return or refund and shipping is non-refundable.
  • No explicit data retention period is stated; de-identified information and results may be used for health research including peer-reviewed scientific research where permitted by law.

No broader panel in the Labbrary catalog lists every biomarker on this one for a lower listed price.

The full breakdown

Eight Dimensions.
One Named Result.

Open any row for the reasoning and evidence behind the named result.

Provider-level quality is directly evidenced: CLIA Certified, CAP Accredited, CLEP Permitted, NY Approved; each assay validated against reference methods for clinical equivalence; accuracy guarantee; named Lab Director and Medical Director. Material gaps keep this at partial: the exact performing facility is unnamed, no per-offer assay methods are published, and no numerical analytical performance is published. Limitation: Exact performing laboratory, assay methods, and offer-specific analytical performance are unpublished.

The exact biomarker page maps each category to its health target with functional descriptions (hormone balance to energy/mood/libido/body composition; thyroid to metabolism/energy/body temperature/weight; heart markers to cardiovascular health; metabolic markers to nutrient availability/energy metabolism/blood sugar balance; CBC to oxygen carrying capacity; kidney/liver markers to filtration and organ health). These are first-party functional claims; independent authoritative grounding in the record currently covers cholesterol guidance only, so target relevance honestly reaches partial, not supported. Limitation: Independent authoritative grounding beyond cholesterol guidance is not established in this pass.

The exact biomarker page gives a complete itemized inventory of 25 actually measured blood biomarkers with sex-specific tags, separated from 5 calculated ratios and 4 derived insights. Coverage can honestly reach supported. Watchout: the Terms allow Rythm to withhold or remove biomarker results and to change the panel at any time, so per-order fulfillment of the full list is not guaranteed. Limitation: No additional material limitation beyond the stated evidence boundary.

Results are presented in an online dashboard with trends, personalized AI insights, and per-category functional descriptions of each marker. Material gap: Rythm explicitly does not provide medical advice and does not interpret test results; only a licensed healthcare professional who knows the customer's history can interpret them, and no clinician result review is included. Limitation: No clinician interpretation or result review is included with the offer.

Seller identity, exact biomarker inventory, lab system description, and full terms/privacy/refund policies are published. Material gaps: exact performing facility unnamed, assay methods unpublished, turnaround has no fixed commitment and varies, and biomarker availability per panel is not guaranteed. Limitation: Exact facility, methods, fixed turnaround, and guaranteed biomarker availability are unpublished.

True at-home self-collection with painless collection, kit ships within 1 business day, free home pickup, direct online checkout, monthly flexible subscription (skip up to 90 days, cancel anytime without fees), and Terms applying in all 50 states plus D.C. for U.S. residents 18+. Limitation: No additional material limitation beyond the stated evidence boundary.

Regular $79.00 per month plus shipping and tax (temporary $59.25 Labor Day promotion noted), HSA/FSA eligibility stated on the exact product page, 30-day money-back guarantee with first-purchase-only conditions documented, skip and cancel terms published, subsequent-order refund policy published. Limitation: No additional material limitation beyond the stated evidence boundary.

Comprehensive first-party privacy posture: no sale or sharing of health information without explicit consent under HIPAA guidelines; access, correction, deletion, and appeal rights; sharing categories enumerated (accredited labs, healthcare providers including partner telehealth clinicians, service providers including AI providers, authorities, business transferees); de-identified research use disclosed; consumer health data policy for CT/NV/WA. Watchout: no explicit data retention period is stated. Limitation: No additional material limitation beyond the stated evidence boundary.

Reading the labels

What Has Been Checked?

Source collected

Evidence labels stay separate from the Test Grade. They show how much source support exists for the evaluation.

The balance

The Strengths. The Tradeoffs.

Strengths

  • Includes named biomarkers across multiple wellness domains, with longitudinal trends and derived insights.
  • At-home blood collection and free home pickup make repeated testing easier.
  • HSA/FSA eligibility, fee-free cancellation, and skips of up to 90 days make the monthly subscription easier to control.

Watch-outs

  • Inclusions differ by sex. Hematocrit and hemoglobin are male-only; free T3, free T4 and progesterone are female-only. The combined list also includes derived insights, so it is not a count of biomarkers measured for every customer.
  • The regular subscription costs $79 per month, and shipping and tax are additional. The displayed $59.25 Labor Day price is promotional.
  • Confirm the performing laboratory and assay methods before ordering.
  • Personalized AI insights, derived scores, and coaching are not medical advice, a diagnosis, or a treatment plan.
  • Results are estimated within 48 business hours when the kit is returned within seven days of receipt. Confirm the current processing estimate before ordering.
