Take the Behavioral QuizThe Silent Epidemic
Obstructive sleep apnea affects an estimated 936 million adults worldwide aged 30–69, yet approximately 80% remain undiagnosed. The consequences of untreated sleep apnea extend far beyond snoring: elevated cardiovascular risk, metabolic dysfunction, cognitive impairment, and dramatically reduced sleep quality — all reflected in chronically low sleep scores.
Home Sleep Apnea Tests (HSATs): Convenience with Tradeoffs
Home sleep apnea tests measure airflow, respiratory effort, blood oxygen saturation, and heart rate. They do not record brain activity (EEG), leg movements, or eye movements — meaning they cannot stage sleep or detect non-OSA sleep disorders.
When HSATs Are Appropriate
- Moderate-to-high clinical suspicion of OSA based on symptoms
- No significant comorbidities (heart failure, COPD, neuromuscular diseases)
- Follow-up testing after CPAP therapy initiation
- Insurance pre-authorization requirement
In-Lab Polysomnography: The Gold Standard
Polysomnography (PSG) records 16+ physiological channels simultaneously: EEG (brain waves), EOG (eye movements), EMG (muscle activity), ECG, airflow, respiratory effort, oxygen saturation, body position, and snoring. This comprehensive dataset enables precise sleep staging, arousal quantification, and detection of any sleep disorder.
When Lab PSG Is Necessary
- Failed or inconclusive home test
- Suspected central sleep apnea or complex sleep-disordered breathing
- Pediatric evaluation
- High clinical suspicion of other disorders (narcolepsy, REM sleep behavior disorder, severe PLMD)
Making Your Decision
If you snore and have daytime sleepiness, start with a home test — it is faster, cheaper, and diagnostically adequate for most moderate-to-severe OSA cases. If your symptoms are complex or your home test is inconclusive, proceed to in-lab PSG. Either way, treatment of confirmed OSA reliably improves sleep scores by 15–25 points within weeks of consistent CPAP use.

Frequently Asked Questions
How accurate are home sleep apnea tests?
Home sleep apnea tests (HSATs) have a sensitivity of 79–98% and specificity of 67–98% for moderate-to-severe obstructive sleep apnea. They are less accurate for mild OSA and cannot detect central sleep apnea or other sleep disorders.
How much does a home sleep apnea test cost?
Home sleep tests typically cost $150–$500 without insurance, or may be covered fully by insurance with a physician referral. In-lab polysomnography costs $1,000–$5,000 without insurance.
What are the symptoms of sleep apnea?
Key symptoms include loud snoring, gasping or choking during sleep (reported by a partner), excessive daytime sleepiness despite adequate time in bed, morning headaches, difficulty concentrating, and elevated WASO. Our behavioral questionnaire includes sleep apnea screening questions.
