Why Sleep Testing Shouldn’t Mean a Night in a Hospital Bed
For most people, the idea of a sleep study means an unfamiliar hospital room, a stiff bed, wires taped to your scalp, and a technician watching through a camera — all while you’re trying to fall asleep naturally. Ironically, the test designed to capture your normal sleep often takes place in the least normal environment possible.
At Australian Polyclinic, we’ve solved this problem. We now offer a full 27-channel polysomnogram (PSG) performed entirely in the comfort of your own home — measuring every parameter recorded in an in-hospital Level 1 sleep study, with the single difference being that the test is unattended (no technologist watching in real time through the night). Because that one factor — in-person, continuous supervision — is what technically defines the classification, this is best described as a Level 2 study by the book, but a Level 1 study in every parameter it measures under supervision of Dr G Sarwar Chaudhry. In practice, that means you get maximum diagnostic depth without ever leaving your own bed.
Sleep Study Levels, Explained Honestly
Sleep studies are classified by two things: how many physiological signals (“channels”) they record, and whether a technologist is physically present monitoring you overnight.
- Level 3 (home sleep apnoea test / HSAT): A limited set of channels — usually airflow, respiratory effort, and oxygen levels only. Useful for straightforward screening of moderate-to-severe obstructive sleep apnoea, but it cannot stage sleep, detect arousals, or diagnose most other sleep disorders.
- Level 2 (unattended full PSG): Records the complete parameter set of an in-hospital study, but is done without a technologist present in the room overnight.
- Level 1 (in-hospital, attended PSG): The traditional gold standard — the same full parameter set as Level 2, plus continuous, in-person technologist monitoring throughout the night.
Where our home study sits: by strict definition, an at-home study is classified as Level 2, simply because there is no technologist physically in the room overnight. But every parameter measured, every sensor applied, and every channel recorded is identical to what’s done for a Level 1 study in hospital. We are not simplifying the test to make it portable — we are recording the full diagnostic picture and just removing the requirement to sleep in an unfamiliar hospital bed.
What We Actually Record: Full 27-Channel PSG
Our home sleep study captures 27 channels, matching in-hospital polysomnography:
- Brain activity (EEG) — multiple leads to accurately stage sleep (light, deep, and REM sleep) and detect arousals
- Eye movement (EOG) — to identify REM sleep
- Limb muscle activity (EMG) — including leg sensors dedicated to detecting Restless Legs Syndrome (RLS) and Periodic Limb Movement Disorder (PLMD), conditions that are frequently missed by basic home tests
- Jaw muscle activity via cheek EMG leads — specifically to detect bruxism (teeth grinding), another common but under-diagnosed cause of disrupted sleep and morning jaw pain or headaches
- Heart rhythm (ECG)
- Airflow and respiratory effort (chest and abdominal bands)
- Oxygen saturation (SpO₂)
- Body position and snoring sensors
This is the same breadth of data a hospital-based Level 1 study collects — sleep architecture, respiratory events, cardiac rhythm, limb movements, and jaw activity — all recorded overnight in your own bed.
How This Differs from a Standard Home Sleep Apnoea Test (HSAT)
It’s worth being clear about this, because “home sleep test” often gets used loosely. A common HSAT (Level 3) measures only airflow, breathing effort, and oxygen levels — typically 4 to 6 channels — and is designed purely to flag obstructive sleep apnoea. It cannot tell you whether you actually reached deep sleep or REM sleep, cannot detect leg movements or bruxism, and can under-diagnose patients whose main problem isn’t apnoea at all. Our home study is a different category of test entirely: a full 27-channel polysomnogram, capable of diagnosing sleep apnoea, RLS/PLMD, bruxism, and abnormal sleep architecture in the same sitting — it simply happens to take place at home instead of in a hospital bed.
How a Home Sleep Study in Lahore Works
- Consultation with Dr. G. Sarwar Chaudhry (FRACP, FCCP) to review your symptoms — snoring, daytime fatigue, witnessed apnoeas, restless legs, jaw pain, or insomnia — and confirm the study is right for you.
- Equipment fitting — two options to suit you:
- Set up at the clinic: visit Australian Polyclinic in DHA Phase 5 in the evening, where our technologist fits the complete 27-channel sensor array, then you head home to sleep in your own bed; or
- Set up at home: our technologist comes to you, fitting all sensors — EEG, EOG, EMG (including leg leads for RLS/PLMD and cheek leads for bruxism), ECG, airflow, respiratory bands, and oximetry — in your own room.
- Sleep naturally, in your own bed, with your own pillow, your own room temperature, and none of the anxiety of an unfamiliar environment. This alone often produces more representative results than a first night in an unfamiliar lab.
- Overnight recording captures every sleep stage, respiratory event, limb movement, and jaw movement, channel by channel, at the same fidelity as an in-hospital PSG.
- Equipment return the next morning — either dropped back at the clinic or collected by our technologist, depending on the setup option you chose.
- Identity card (NIC): we will ask you to submit your national ID card for the night of sleep study. It is returned back
- Physician-reported results. Dr. Chaudhry personally scores and interprets the full study, and discusses the diagnosis and treatment plan with you — whether that’s CPAP titration, RLS/PLMD management, a bruxism guard referral, or further specialist assessment.
Why This Matters for Patients
- More natural sleep, more accurate diagnosis. Many patients sleep poorly on their first night in an unfamiliar lab bed — a well-known effect called the “first-night effect” — which can under- or over-estimate severity. Home testing removes that variable.
- No hospital admission, no overnight stay away from family. Ideal for patients with mobility issues, caregiving responsibilities, or simply a preference for privacy.
- Full diagnostic depth, not a screening shortcut. Because it records brain-wave-level detail across 27 channels, this study can distinguish between obstructive sleep apnoea, central sleep apnoea, restless legs syndrome, periodic limb movement disorder, bruxism, and other causes of poor sleep that basic home tests simply cannot detect.
- Flexible setup, either at the clinic or at your home, in DHA Lahore and surrounding communities.
Who Should Consider a Sleep Study?
You may benefit from a sleep study if you experience:
- Loud, habitual snoring or witnessed pauses in breathing during sleep
- Excessive daytime sleepiness despite a full night in bed
- Morning headaches or a dry mouth on waking
- Difficulty concentrating, memory lapses, or mood changes linked to poor sleep
- High blood pressure, irregular heart rhythm, or unexplained weight gain
- A partner who has noticed gasping, choking, or restless leg movement at night
- Uncomfortable, “restless” sensations in the legs at night, or a partner noticing kicking or jerking movements
- Jaw pain, worn-down teeth, or headaches on waking, which can point to nighttime teeth grinding (bruxism)
If any of this sounds familiar, a proper diagnostic sleep study — not just a symptom checklist — is the only way to know what’s really happening while you sleep.

Frequently Asked Questions
Is this a Level 1 or Level 2 sleep study? Technically, it’s a Level 2 study — because it’s unattended, meaning no technologist is physically in the room monitoring you overnight. However, it records the exact same 27 channels and parameters as an in-hospital Level 1 study, including EEG, EOG, EMG (leg and jaw leads), ECG, airflow, respiratory effort, and oxygen saturation. The only thing missing compared to Level 1 is in-person supervision — not diagnostic depth.
How is this different from a basic home sleep apnoea test (HSAT)? A standard HSAT (Level 3) records only 4–6 channels — airflow, effort, and oxygen — and can only screen for obstructive sleep apnoea. Our study records 27 channels, the same breadth as a hospital PSG, so it can also diagnose restless legs syndrome, periodic limb movement disorder, bruxism, and abnormal sleep architecture, not just apnoea.
Can this study detect restless legs syndrome (RLS) or teeth grinding (bruxism)? Yes. We use dedicated leg EMG leads to detect RLS and periodic limb movements, and cheek EMG leads over the jaw muscles to detect bruxism — both of which are missed entirely by standard home apnoea tests.
Where does the equipment get fitted — at the clinic or at home? Either. You can come to Australian Polyclinic in DHA Phase 5 in the evening for the technologist to fit the sensors before heading home, or our technologist can visit your home to set everything up there. Both options result in the same full overnight recording.
Do I need to book a sleep study at Australian Polyclinic? Yes. You need to book a consultation directly with Dr. Chaudhry, who will assess your symptoms and determine whether a sleep study is appropriate.
How long does the sleep study take? The study runs overnight, typically 7–8 hours, matching your normal sleep schedule.
Will I get my results explained by a doctor, or just a printed report? Dr. Chaudhry personally reviews and scores each study and discusses the results and next steps with you directly, rather than issuing an automated report alone.
