UM Researchers Develop 86%-Accurate Sleep Apnea Test, Cutting Diagnosis to 4 Minutes
1 articles · Updated · umtoday.ca · May 29
UM researchers Zahra Moussavi and Walid Ashraf published a sound-based sleep apnea test that screened patients with 86% accuracy in pilot studies using a five-minute breathing test while patients were awake.
The patented setup uses a contact microphone on the neck and a small speaker in the mouth to map airway shape, aiming to identify the exact cause and location of obstruction rather than only confirming apnea.
That could sharply improve access in Manitoba, where testing relies on one Winnipeg sleep clinic with waits of more than a year and overnight monitoring with electrodes.
Current surgical treatment succeeds only about 50% of the time because existing tests often cannot pinpoint the underlying cause, the researchers said.
The project remains in the research stage and needs more participants plus CT-scan validation before the team can market a device they say could be used by nurses or family physicians.
This new test is 86% accurate, but can it ever truly replace the gold-standard overnight sleep lab study?
With a year-long wait for diagnosis, how quickly can this sound-based test get validated and into doctors' hands?
Sleep Apnea in 2026: Evaluating the "86%-Accurate, 4-Minute Test" Claim and the University of Miami’s Role in Rapid, AI-Driven Diagnostics
Overview
This report examines the current state of sleep apnea diagnostics, highlighting that the widely circulated claim of an '86%-accurate, 4-minute sleep apnea test' from the University of Miami is not directly supported by available evidence. Instead, it emphasizes the University of Miami Miller School of Medicine’s recognized leadership and ongoing commitment to advancing sleep medicine, particularly through active research and patient-centered care. The institution conducts comprehensive sleep studies and is deeply involved in efforts to address obstructive sleep apnea, reflecting a broader trend of innovation and dedication to improving diagnosis and treatment in this critical health field.
