Introduction: The Sleep Test That Tells You Everything — At Home
Most people have heard of a sleep study. Far fewer know that there are different levels of sleep testing — and that Level 2 sleep study is the most comprehensive home-based diagnostic option available today. If you've been advised to get a sleep test but want to avoid an overnight hospital stay, a Level 2 portable sleep study could be exactly what you need.
BreatheNest is making Level 2 sleep studies accessible across India — with home delivery of clinical-grade equipment, specialist-reviewed reports, and end-to-end support from booking to diagnosis. Here's everything you need to know.
What Are the Levels of Sleep Studies?
Sleep studies are classified into four levels by the American Academy of Sleep Medicine (AASM) — a framework now widely adopted by sleep specialists in India:
Level 1 — In-Lab Polysomnography (PSG) The gold standard. Conducted in a sleep laboratory with a technician present throughout the night. Records 16+ channels of data including brain waves, eye movements, muscle activity, heart rhythm, breathing, and oxygen levels. Most comprehensive but most expensive and least convenient.
Level 2 — Unattended Full Polysomnography (Home PSG) The same comprehensive data as Level 1 — but conducted at home, without a technician present. Records a minimum of 7 channels including EEG, EOG, EMG, ECG, airflow, respiratory effort, and SpO₂. Clinically equivalent to Level 1 for most sleep disorder diagnoses.
Level 3 — Cardiorespiratory Sleep Study Records 4–7 channels focused on breathing and oxygen — no EEG or EMG. Suitable for straightforward OSA screening but misses neurological sleep data.
Level 4 — Continuous Single Bioparameter Records only one or two signals — typically SpO₂ or airflow. Used for basic overnight oxygen monitoring, not full diagnosis.
For patients who need a complete, clinician-grade sleep diagnosis at home, Level 2 is the ideal choice.
What Does a Level 2 Sleep Study Measure?
A Level 2 home sleep study captures the same rich diagnostic data as an in-lab test:
- EEG (Electroencephalogram) — Brain wave activity to identify sleep stages
- EOG (Electrooculogram) — Eye movements to detect REM sleep
- EMG (Electromyogram) — Chin and leg muscle activity for movement disorders
- ECG (Electrocardiogram) — Heart rhythm and rate throughout the night
- Nasal Airflow — Breathing pattern and apnea events
- Respiratory Effort — Chest and abdominal movement belts
- SpO₂ — Blood oxygen saturation levels
- Body Position — Positional OSA detection
- Snoring Intensity — Via microphone sensor
This comprehensive dataset allows sleep specialists to diagnose a full range of conditions — including obstructive sleep apnea, central sleep apnea, hypopnea, REM sleep behavior disorder, periodic limb movement disorder, and narcolepsy.
Level 2 vs Level 3 Sleep Study: Which One Do You Need?
| Feature | Level 2 | Level 3 |
|---|---|---|
| Channels Recorded | 7+ (full PSG) | 4–7 (cardiorespiratory) |
| EEG (Brain Waves) | Yes | No |
| Sleep Staging | Yes | No |
| REM Detection | Yes | No |
| Movement Disorders | Yes | No |
| OSA Diagnosis | Yes | Yes |
| Narcolepsy / RBD | Yes | No |
| Location | Home | Home |
| Ideal For | Complete diagnosis | OSA screening only |
If your doctor suspects complex sleep disorders beyond simple OSA, a Level 2 sleep study is the clinically appropriate choice.
Level 2 Sleep Study Price in India
One of the most searched questions is: "What is the Level 2 sleep study price in India?"
Here is a realistic comparison:
- Level 1 In-Lab PSG: ₹12,000 – ₹25,000 per night
