A home sleep test is a sleep study tool that can be used to monitor a person's sleep patterns in the comfort of their own home, rather than in a sleep laboratory. It is a non-invasive method of testing that uses portable devices to monitor their sleep at home. These tools usually include a variety of sensors that measure different aspects of sleep, such as brain waves, eye movements, muscle activity, and breathing patterns. The data collected by the sensors is then analyzed by the sleep specialist and the report is generated on the detected sleep disorder. An appropriate treatment will be recommended for the patients. Home sleep study tools can be used as an alternative to in-lab polysomnography (PSG) for the diagnosis of sleep disorders and can be prescribed by a healthcare provider.
