3. How does a home sleep test compare to a hospital or freestanding sleep lab test?

Polysomnography, (PSG) is the gold standard test for diagnosing all forms of sleep disordered breathing. Obstructive sleep apnea (OSA) is by far the most prevalent form of sleep disordered breathing. For diagnosing obstructive sleep apnea, (OSA) the home sleep test (HST) correlates 98% with PSG. · A home test is often a more convenient and economical option compared with a PSG study, and offers more representative sleep data – the patient is tested in their normal home sleeping environment rather than a laboratory. The cost of a PSG is $ 3,000 - $ 5,000; the cost of an HST is typically 10% of the cost of a polysomongram.
