How does DROWZLE differ from a Home Sleep Test (HST) or Polysomnography (PSG) testing?

Briefly outlines differences between OSA screening and diagnostic testing options.

Home sleep testing (HST) and polysomnography (PSG - sleep lab testing) are detailed tests used to confirm the diagnosis of obstructive sleep apnea (OSA). DROWZLE is a screening test used to identify those at risk for OSA who then should consult with a medical provider for next steps, including PSG or HST testing, if appropriate.
