Rythm (Rythm Health) is a San Francisco-based consumer laboratory testing company that sells an at-home, fingerstick-style blood test marketed as "The World's Easiest Blood Test." Customers order a kit that ships within one business day, collect a sample at home, and return it by mail or scheduled pickup; results are reported in under 48 hours through the company's platform with explanations of what each marker means. The standard panel covers 25 or more biomarkers, and the service is available in all 50 US states.

The company operates its own laboratory, described on its site as the Rythm Lab, which it says is HIPAA compliant, CLIA certified, CAP accredited, CLEP permitted and New York approved. Rythm states that it owns every step from kit to result, validates each assay against reference methods to establish clinical equivalence with traditional venous draws, and backs results with a clinical accuracy guarantee. It frames its mission as advancing universal health literacy by making high-quality health data affordable and broadly accessible.

The leadership team listed by the company includes Robby Wade (Co-Founder & CEO), Dacri Burdan (Co-Founder & CTO), Dr. Zhiyi Qiang (Co-Founder & CLO, Lab Director), Kelsie Muir (Co-Founder & CDO), Devon Levesque (Co-Founder & Creative Director), Dr. Jeffrey Graham (Medical Director), Dr. Melissa Keinath (Chief Science Officer) and Dr. Bing Wang (Data Science Director).
