What they did and found
We tested AI systems on WearableQA, a dataset of real users’ wearable time series, blood biomarkers, and basic demographics. Results showed accuracy from 19.6% to 72.9%, with most models below 60%, revealing uneven abilities and ongoing data challenges.
Why it matters
This warns against over‑relying on AI for health readings and points to where users and regulators should demand solid evidence.
WearableQA looks at how an AI system handles long daily data and combines health signals over time, not just short facts.
Even strong models struggle to merge signals across days, so human oversight remains important for nuanced health decisions.
