In-Lab Sleep Study

When your sleep is complicated — or a home test can't tell the whole story — one night in our AASM-accredited lab gives your physician the complete picture. Private suites, designed to feel like a hotel.

What is an in-lab sleep study?

An in-lab sleep study — the medical name is polysomnography — is an overnight test that records what your body does while you sleep. You spend one night in a private suite in our lab, wearing soft sensors that track your breathing, heart rate, oxygen, brain waves, and body movements all at once.

It's the most complete sleep test available. Because a registered technologist is watching your data live and can adjust things through the night, an in-lab study captures details a take-home test simply can't — which is why it's the right tool for more complex cases.

Who needs an in-lab study?

Many people do great with a simple home sleep test. An in-lab study is recommended when your situation calls for a closer look, such as:

Complex or mixed cases

Suspected central sleep apnea, or symptoms that don't fit a straightforward obstructive picture.

Other health conditions

Heart failure, lung disease, or neuromuscular conditions that make home testing less reliable.

Beyond apnea

Evaluating narcolepsy, periodic limb movements, restless legs, or unusual nighttime behaviors.

When home testing falls short

A home test came back unclear or negative, but your symptoms are still very real.

Not sure which test is right for you? That's exactly what your consultation is for — your physician will recommend the least involved test that will give a clear answer.

Your night, step by step

Knowing what to expect takes most of the nerves out of it. Here's how the evening usually goes:

Arrival, eveningYou arrive in the evening — around your normal bedtime routine. Bring your pajamas and anything you'd normally need to sleep. Get settled, brush your teeth, and relax in your private room.

Sensor setupYour technologist gently places soft sensors and small patches on your scalp, face, chest, and legs, plus a clip on your finger. It's painless, takes about 30–45 minutes, and nothing pierces the skin.

Lights outYou settle into bed and sleep as normally as you can. Most people sleep more than they expect. If you need to get up during the night, your tech is just a call away and can quickly disconnect you.

Through the nightFrom a separate room, your registered technologist monitors your data live and makes sure every signal is clean. You won't be disturbed unless something needs a quick adjustment.

Morning wake-upYou're woken at your usual time. The sensors come off in minutes, you can freshen up, and you head out to your normal day — often before your morning coffee is cold.

Sometimes the night is run as a "split-night" study: if clear, significant apnea shows up in the first half, your technologist can start CPAP and fine-tune the pressure (a titration) during the same night — so a single visit both confirms the diagnosis and begins treatment.

Rooms that feel like a hotel, not a hospital

We know the idea of "sleeping in a lab" sounds strange. That's why our suites are built for comfort: a real, comfortable bed, soft lighting, a private bathroom, and a quiet, temperature-controlled room. No clinical glare, no roommates, no hospital sounds — just a calm space designed to help you actually fall asleep.

The only real difference from a hotel is the team quietly making sure we capture everything your physician needs.

After your study

You go home with a plan, not just a printout

Your overnight recording holds thousands of data points. A board-certified sleep physician reviews it in detail, then sits down with you to explain what it means and what comes next — in plain language.

In-lab sleep study FAQs

Will I actually be able to sleep with all those sensors?

It's the number-one worry, and the answer is almost always yes. The sensors are soft and lightweight, and our suites are designed for comfort. You don't need a perfect night's sleep — the study only needs enough sleep to capture what your physician is looking for, and most people sleep far more than they expect.

How should I prepare for the night?

Keep your day normal, but skip caffeine and naps in the afternoon. Wash and dry your hair without heavy products so the sensors stick well, and bring comfortable pajamas plus anything from your usual bedtime routine. If you take nightly medications, bring them and let us know. We'll send you a simple checklist when you schedule.

Can I get up to use the bathroom during the night?

Absolutely. Just let your technologist know — they can quickly disconnect the sensors so you can get up, then reconnect you when you're back in bed. You're never locked in place.

How long until I get my results?

Because a physician reviews the full recording in detail, results aren't instant. Your study is scored and read, then you'll meet with your provider — in person or by telehealth — to go over the findings and your plan. We'll give you a clear timeline when you schedule.

Does insurance cover an in-lab sleep study?

Most major Arizona plans and Medicare cover in-lab studies when they're medically indicated. We verify your specific benefits before your night in the lab so there are no surprises. Visit our insurance page or call the office at (602) 206-6262 to check your plan.

What's the difference between an in-lab and a home sleep study?

A home sleep test is simpler and done in your own bed, but it measures fewer signals and works best for straightforward obstructive sleep apnea. An in-lab study measures far more — including brain waves and sleep stages — with a technologist monitoring live, which is why it's used for complex cases or when a home test isn't enough.

Sleep well. Be well.

Complex sleep deserves a complete answer.
