What is a home sleep apnea test (HSAT)?
Last updated: 2026-10-28
Quick answer
A home sleep apnea test (HSAT) is a Level 3 sleep study you do in your own bed to diagnose obstructive sleep apnea. A small device records your airflow, breathing effort, blood oxygen (SpO2), heart rate and body position overnight, and a specialist scores your AHI. It's clinically validated for typical obstructive sleep apnea, far cheaper than an in-lab study, and with SleepEase costs ₹2,500 with the report in 24 hours.
What an HSAT measures
A home sleep apnea test records the core signals needed to detect obstructive sleep apnea: airflow through the nose and mouth, breathing effort from a chest band, blood oxygen (SpO2), heart rate, snoring and body position. From these a specialist scores your AHI (apnea-hypopnea index) and ODI (oxygen desaturation index).
Unlike a full in-lab polysomnography, an HSAT does not record brain waves or sleep stages — it focuses on breathing, which is what matters for diagnosing obstructive sleep apnea in people with typical symptoms.
How accurate is it?
For adults with classic signs — loud snoring, witnessed pauses, daytime sleepiness — a Level 3 HSAT is clinically validated and widely used to diagnose obstructive sleep apnea. Sleeping in your own bed often gives a more representative night than an unfamiliar hospital ward.
Complex cases — suspected central sleep apnea, significant heart or lung disease, or a negative test despite strong symptoms — may still need an attended in-lab study, which your doctor can advise.
HSAT cost and how to book
A SleepEase HSAT is ₹2,500 all-in — the technician's home visit, the device overnight and a scored report on WhatsApp within 24 hours — versus ₹8,000–₹15,000 for an overnight lab study. No referral is needed to book; message us on WhatsApp and a technician comes to your home.
