Sleep Apnea Test at Home: How It Works, What It Measures, and What Your Results Mean
An estimated 936 million adults worldwide have obstructive sleep apnea, and the vast majority don't know it. For decades, diagnosis required an overnight stay in a hospital sleep lab, hooked up to dozens of electrodes. That's changed. FDA-cleared home sleep apnea tests now let you get a clinical-grade diagnosis from your own bed, at a fraction of the cost. The research backing these devices is substantial, and for most adults with suspected moderate-to-severe obstructive sleep apnea, the American Academy of Sleep Medicine considers home testing a validated alternative to in-lab polysomnography.
