Every morning in Delhi, thousands of people wake up tired. They slept eight hours and still feel exhausted. Their partner complains about loud snoring. They have a headache before breakfast. They fall asleep in meetings. They have been told their blood pressure is high — and no one knows why.
The answer, in a large number of these cases, is Obstructive Sleep Apnea (OSA) — a condition where the airway collapses repeatedly during sleep, cutting off oxygen. It affects an estimated 13.7% of urban Indian adults, yet over 90% remain undiagnosed. In Delhi and NCR, where pollution, stress, and sedentary lifestyles amplify the risk, the numbers are likely even higher
A sleep study test — also called a polysomnography or PSG test — is the only way to diagnose this accurately. This guide tells you everything about getting one done in Delhi: what types of tests exist, what each one costs, whether you can do it at home, and how to book without visiting a clinic.
Do You Need a Sleep Study? — Warning Signs to Watch For
Most people who need a sleep study test have been living with symptoms for years without connecting them to a sleep disorder. Here are the signs that indicate you should get tested — and which test is likely right for you.
Symptom | Likely Cause | Test Recommended |
Loud snoring every night | Upper airway obstruction | Level 2 at-home test |
Waking up gasping or choking | Obstructive Sleep Apnea (OSA) | Level 2 or Level 1 PSG |
Extreme daytime sleepiness | OSA, Narcolepsy, PLMD | Level 1 full PSG (lab) |
Morning headaches daily | Oxygen drop during sleep | Level 2 at-home test |
Pauses in breathing (observed by partner) | Central or Obstructive Apnea | Level 1 full PSG (lab) |
Restless legs / leg jerks at night | Periodic Limb Movement Disorder | Level 1 full PSG (lab) |
Sleepwalking / sleep talking | Parasomnias | Level 1 full PSG (lab) |
High blood pressure + snoring | OSA (major BP driver) | Level 2 at-home test |
Frequent night urination | OSA (pressure changes in chest) | Level 2 at-home test |
Child snoring + hyperactivity | Paediatric OSA | Paediatric PSG (lab) |
Important: You do not need to have all these symptoms. Even two or three — particularly loud snoring + daytime sleepiness, or snoring + high blood pressure — are enough clinical justification for a sleep study. Do not wait for the sleep apnea symptoms to become severe
Types of Sleep Study Tests Available in Delhi
Sleep studies are classified into four levels by the American Academy of Sleep Medicine (AASM). In India, Level 1, Level 2, and Level 3 tests are the most commonly offered. Here is what each one measures and who it is right for.
The most comprehensive sleep test available. Conducted overnight at a sleep lab or hospital, with a technician monitoring you throughout the night.
• Measures: Full EEG (brain waves), eye movements (EOG), muscle activity (EMG), ECG, airflow, chest and abdominal effort, blood oxygen (SpO ), body position, snoring
• Diagnoses: OSA, Central Sleep Apnea, Narcolepsy, REM Sleep Behaviour Disorder, Periodic Limb Movement Disorder, Parasomnias
• Best for: Children, complex or unclear cases, patients where an at-home test came back inconclusive, anyone with significant cardiac or neurological history
• Where: Sleep labs at AIIMS Delhi, Fortis, Max, Apollo, Medanta (Gurgaon)
• Duration: One full night (8–10 hours)
Level 1 PSG is the gold standard. If your doctor has asked for a 'full sleep study' or a 'polysomnography', they are referring to Level 1.
The same comprehensive monitoring as Level 1, but conducted at home without a technician present. A portable device is set up by our technician at your home in the evening, worn overnight, and collected the next morning for analysis.
• Measures: EEG, EOG, EMG, ECG, airflow, chest effort, SpO , body position
• Diagnoses: OSA (all severity levels), sleep staging, AHI calculation
• Best for: Adults with moderate-to-severe OSA symptoms who prefer testing at home in their own sleep environment
• Significant advantage: Sleeping in your own bed, in your usual position, with your usual pillows — produces more representative data than a lab
• Not for: Children, suspected narcolepsy or parasomnias
The most popular at-home sleep test in India. Lighter than Level 2 — no EEG — but covers the parameters most needed to diagnose OSA.
• Measures: Airflow (nasal cannula), chest and abdominal effort, blood oxygen (SpO ), pulse rate, snoring, body position
• Does NOT measure: Brain waves, sleep stages
• Diagnoses: Obstructive Sleep Apnea (AHI, RDI), oxygen desaturation index
• Best for: First-time diagnosis in adults with clear OSA symptoms (snoring + daytime sleepiness + witnessed apneas), follow-up testing after CPAP/BiPAP therapy
• Turnaround: Report within 24–48 hours
Level 4 — Overnight Pulse Oximetry (Screening Only)
The simplest screening test — a finger pulse oximeter worn overnight to measure blood oxygen drops. Not a diagnostic test on its own, but useful as an initial screen before a more detailed study. Widely available at pharmacies and online.
Not sure which level you need? Our team will ask you 3–4 quick questions about your symptoms and guide you to the right test before you book. No doctor's referral required for Level 2 and Level 3 at-home tests.

0 – 4 | Normal | No significant sleep apnea | Lifestyle changes if symptomatic |
5 – 14 | Mild OSA | Breathing disturbed 5–14 times/hour | CPAP, weight loss, positional therapy |
15 – 29 | Moderate OSA | Significant oxygen drops overnight | CPAP/BiPAP therapy — start immediately |
30+ | Severe OSA | Breathing severely compromised all night | BiPAP/CPAP — urgent intervention |
Frequently Asked Questions — Sleep Study in Delhi Q: Do I need a doctor's prescription to book a sleep study?
No. You can book a Level 2 or Level 3 at-home sleep study directly without a referral. If you have a prescription or doctor's letter, please share it — our reporting physician will review it alongside your test data.
Q: How long does the test take?
The device is set up in 20–30 minutes in the evening. You wear it overnight for a minimum of 6 hours of data recording. The equipment is collected the next morning. Total involvement: one evening + one morning pickup.
Q: Can I eat and drink normally before the test?
Yes. Eat and drink normally. Avoid alcohol and sedatives on the night of the test as these suppress sleep apnea events and can lead to a falsely normal result. If you take any regular medications, continue taking them as prescribed.
Q: Can I eat and drink normally before the test?
Yes. Eat and drink normally. Avoid alcohol and sedatives on the night of the test as these suppress sleep apnea events and can lead to a falsely normal result. If you take any regular medications, continue taking them as prescribed.
Q: Will I be able to sleep with all the sensors on?
Most patients sleep comfortably with the sensors. The nasal cannula and finger probe are lightweight. The chest belt is elastic and non-restrictive. Some patients take 30–60 minutes longer to fall asleep initially — this is accounted for in the analysis and does not affect results.
Q: What if my test result is inconclusive?
An inconclusive result occurs in a small percentage of at-home tests — usually due to sensor displacement during sleep. In this case, we repeat the test at no additional charge. If the second test is also inconclusive, we will recommend an in-lab Level 1 PSG.
Q: How quickly will I get my report?
Level 2 and Level 3 at-home test reports are delivered within 24–48 hours of equipment collection, via email and WhatsApp. Reports are signed by a certified sleep physician.
Q: Is the at-home sleep test accurate?
Level 3 at-home sleep tests have been validated in multiple clinical trials and are accepted by the American Academy of Sleep Medicine (AASM) and Indian sleep medicine guidelines for the diagnosis of moderate-to-severe OSA in adults. Studies show 85–90% agreement with full in-lab PSG for OSA diagnosis.
Q: Can children take the at-home sleep test?
No. Children under 18 require an attended Level 1 PSG conducted in a paediatric sleep lab. The at-home test is not validated for paediatric use and cannot diagnose the range of conditions that affect children's sleep.
Q: I snore but feel fine during the day. Should I still get tested?
Yes. Daytime sleepiness is absent in 30–40% of OSA patients, particularly younger adults and those with moderate OSA. Snoring alone — especially loud, regular snoring — is a significant risk factor. Untreated OSA increases the risk of hypertension, heart disease, stroke, and Type 2 diabetes regardless of whether you feel sleepy during the day.
Q: What is the difference between AHI and RDI? AHI (Apnea-Hypopnea Index)
counts the number of complete and partial airway obstructions per hour. RDI (Respiratory Disturbance Index) is broader — it also includes subtle breathing irregularities (RERAs) that don't fully meet the threshold for apneas. Your report will include both. RDI is typically slightly higher than AHI.
Q: Can I book a sleep study test as a gift for a family member? Yes. Many families book the test for elderly parents or spouses who are reluctant to seek medical attention. You can book in someone else's name and be present during the device setup. Our technicians are trained to handle patients who are nervous or unfamiliar with medical devices.
