Quest Embeds AI Into Core Lab Infrastructure
- Quest is embedding generative AI into its MyQuest portal to analyze up to five years of patient lab data inside a HIPAA-compliant environment.
- Powered by Google's Gemini models, the chatbot identifies trends, explains results, and helps patients prepare questions for doctors, keeping Quest central to consumer lab insights.
Independent Certification Reveals Widespread Supplement Inaccuracy
- Subco launched Tested, a certification that anonymously buys retail supplements and verifies active ingredients in independent labs to hold brands accountable.
- Its internal analysis found roughly half of top-selling supplements failed label accuracy, and passes (≥95%) are published publicly to drive trust.
8Sleep Moves From Reactive Pods To Predictive Health
- 8Sleep raised new funding at a $1.5 billion valuation and is shifting from reactive temperature-based sleep optimization to predictive AI-driven sleep agents.
- Having trained models on more than 1 billion hours of sleep data, 8Sleep plans scenario simulations and seeks FDA clearance for sleep apnea detection to enter regulated healthcare.
