AI Tools Fail to Identify Validated BP Monitors
TLDR
- Google Gemini outperformed ChatGPT, Copilot and Perplexity in identifying validated home blood pressure monitors, scoring up to 91 percent accuracy.
- Researchers tested 324 blood pressure monitors using four AI tools with three question types and retested twenty percent across different days and computers.
- Relying on inaccurate AI for blood pressure monitor validation may lead to wrong diagnoses and treatments, so verify devices via validatebp.org.
- AI tools often failed to recognize validated blood pressure monitors, sometimes giving different answers on different days, which shows their answers are not stable.
Impact - Why it Matters
This research matters because inaccurate AI responses could lead patients to unknowingly use unvalidated home blood pressure monitors, resulting in false readings that may lead to inappropriate diagnoses or treatments. With high blood pressure being the number one risk factor for cardiovascular disease and only a quarter of affected adults under control, ensuring device accuracy is critical. The study underscores that AI, despite its promise, is not yet reliable for verifying medical device validation, and patients should rely on official registries like validatebp.org.
Summary
Three of the four leading AI-powered search tools—OpenAI’s ChatGPT, Microsoft’s Copilot, and Perplexity AI—could not consistently identify home blood pressure monitors that met clinical validation standards, according to preliminary research presented at the American Heart Association’s Hypertension Scientific Sessions 2026 in Arlington, Virginia. The study, led by Dr. Anna Soriano of the University of Montreal, tested 324 monitors (145 validated, 179 not) against Google Gemini, Microsoft Copilot, ChatGPT, and Perplexity. Accuracy for ChatGPT, Copilot, and Perplexity ranged only from 63% to 83%, while Google Gemini performed best at 86% to 91% but still erred 10% to 15% of the time. All four tools were less accurate at identifying validated devices versus unvalidated ones, and when retested on different days or computers, they often gave inconsistent answers.
The findings raise serious concerns because high blood pressure affects more than 125 million U.S. adults, yet only about 1 in 4 have it under control. The 2025 American Heart Association Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults recommends using a validated home monitor, and people can check www.validatebp.org for listings. Dr. Keith C. Ferdinand, an AHA volunteer expert, cautioned that AI’s shortcomings should remind clinicians and the public that using AI for clinical decisions requires caution. Researchers advise confirming validation through recognized independent registries like validatebp.org. The study is preliminary and not peer-reviewed.
