Where the Comparison Starts and Ends

People ask because both companies offered blood testing without a clinic visit. That's the entire overlap.

What Rythm Actually Does

Rythm uses an FDA-cleared device (Tasso+) to collect a standard capillary specimen into the same Microtainer tubes used throughout traditional healthcare. That sample is tested in Rythm's own CLIA-certified, CAP-accredited laboratory, on FDA-regulated analyzers, using validated, transparent clinical assays with published, peer-reviewed evidence behind the collection method itself.

What Theranos Claimed

Theranos said it could run hundreds of tests on tiny volumes using proprietary instruments that were never validated, never FDA-cleared for broad clinical use, and never proven comparable to standard methods.

Frequently Asked Questions

How is Rythm different?

Most blood testing companies charge $500 or more for a single test per biomarker, providing only a one-time snapshot that doesn’t capture your long-term health trends or reflect your true baseline. This approach can lead to missed patterns or even misdiagnoses due to limited data. Rythm takes a different approach, using monthly tracking to build a detailed picture of your health over time. This allows for more accurate insights, better optimization, and a clearer understanding of how your body is evolving.
