A Home Sleep Test (HST) is a convenient, simplified diagnostic tool used to assess sleep disorders, particularly obstructive sleep apnea (OSA), in the comfort of a patient’s home. The test involves wearing a portable device overnight that monitors breathing patterns, oxygen levels, heart rate, and airflow. Unlike in-lab sleep studies (polysomnography), which require a hospital or sleep clinic setting, the home sleep test is less complex and focuses on gathering data related to sleep-disordered breathing. HST is widely used for diagnosing moderate to severe sleep apnea, providing an accessible, cost-effective alternative to in-lab testing for eligible patients.
