What is a Sleep Apnea Test?
A sleep apnea test (also called a sleep study or polysomnography) records body functions while you sleep — breathing, oxygen levels, heart rate, snoring and body movements. It helps diagnose obstructive and central sleep apnea, severe snoring, and other sleep-related breathing disorders.
Types of Sleep Apnea Tests & Typical Price Ranges in Delhi
The cost depends on the test type (home vs in-lab), device complexity and specialist review. Below are realistic ranges seen across Delhi NCR.
| Test Type | What it measures | Typical Price Range (Delhi) |
|---|---|---|
| Home Sleep Test (Level 3) | Airflow, oxygen (SpO₂), heart rate, snoring — portable single-night study | ₹4,500 – ₹6,000 |
| In-Lab Polysomnography (Full PSG) | EEG, ECG, EMG, airflow, SpO₂, respiratory effort — multi-channel gold standard | ₹7,500 – ₹12,000 |
| Advanced / Multi-night Studies | Extended monitoring or two-night studies for complex cases | ₹10,000 – ₹20,000 |
Note: Prices vary by device level, technician experience, city zone and whether a sleep physician reviews the report. Choose by test level and report quality, not just lowest price.
Factors That Affect Sleep Apnea Test Cost
- Test type: home-level (lower) vs in-lab PSG (higher).
- Device & channels: more channels = higher cost (EEG/ECG/respiratory effort increase cost).
- Specialist review: pulmonologist/sleep physician sign-off adds to price but increases diagnostic value.
- Duration & repeat studies: multi-night or split-night studies cost more.
- Home visit charges: technician travel/time may be added for home tests.
- City & location: premium clinics in central Delhi often charge higher than peripheral areas.
Home Sleep Test vs In-Lab PSG — Which Should You Choose?
Home Sleep Test is reliable for most patients suspected of moderate-to-severe obstructive sleep apnea and is more comfortable and affordable. In-lab PSG is recommended for complex or unclear cases (neurological disorders, suspected central apnea, or when the home test is inconclusive).
| Feature | Home Sleep Test | In-Lab PSG |
|---|---|---|
| Comfort | High — sleep in familiar surroundings | Lower — sleep in lab/clinic |
| Accuracy | High for moderate/severe OSA | Highest (gold standard) |
| Cost | Lower | Higher |
| Supervision | Minimal (technician setup) | Continuous monitoring by staff |
How the Test Works — Step by Step
- Book appointment with the diagnostic centre or online.
- Receive pre-test instructions (avoid heavy alcohol, follow medication guidance).
- Technician sets up the device at home or you arrive at the lab in the evening.
- Overnight recording — device collects data while you sleep (usually 7–8 hours).
- Device returns to the lab; data analysed by sleep specialist.
- Receive clinician-reviewed sleep study report and consultation.
Why Early Sleep Testing Matters
Untreated sleep apnea increases the risk of hypertension, heart disease, stroke, diabetes and daytime accidents. Early diagnosis helps start treatments such as CPAP therapy, oral appliances, lifestyle change, or surgical referral where necessary.
