Dr. Charles Mok explains how to screen and diagnose obstructive sleep apnea using the STOP-BANG questionnaire and partner reports (snoring, witnessed apneas). He defines the apnea–hypopnea index as the key diagnostic measure and contrasts in-lab sleep studies (the long-standing gold standard) with at-home testing devices, noting that at-home tests are generally acceptable for otherwise healthy patients while in-lab testing is preferable for patients with significant comorbidities; he also mentions convenience, expense, and insurance coverage as practical considerations.
