Two Paths to Better Sleep Health
If a doctor or telehealth provider has suggested you be evaluated for a sleep disorder, you may have been told there are two main ways to do it: a home sleep test (HST) or an in-lab sleep study, also called a polysomnography or PSG. Both are designed to capture information about what your body does while you sleep, but the experience of each is quite different. Understanding what each involves can help you have a more informed conversation with your care team.
How a Home Sleep Test Works
A home sleep test lets you sleep in your own bed while wearing a small monitoring device. The device is typically mailed to you or picked up at a provider's office. Setup is straightforward — most people can get everything connected in just a few minutes using the instructions provided.
During the night, the device records data such as:
- Airflow through your nose and mouth
- Breathing effort from your chest and abdomen
- Blood oxygen levels
- Heart rate
- Body position and movement
In the morning, you remove the device and either return it or upload the data, depending on the provider. A sleep specialist then reviews the results and shares a report with you, often within a few days.
Many people appreciate home sleep tests because they're convenient and less disruptive to a normal nightly routine. Sleeping in your own environment, in your own bed, often makes it easier to fall and stay asleep compared to an unfamiliar clinical setting.
How an In-Lab Sleep Study Works
An in-lab study is conducted at a sleep center or hospital-based clinic. You arrive in the evening, and a trained sleep technologist attaches a more extensive set of sensors before you go to sleep. These typically monitor everything a home device does, plus additional signals like:
- Brain wave activity (EEG)
- Eye movements
- Muscle activity in the legs and chin
- A full video recording of your sleep
The broader range of data collected in a lab makes it possible to evaluate a wider variety of sleep conditions, not just breathing-related ones. Sleep specialists often recommend an in-lab study when there's reason to look at sleep stages in detail, or when certain less common sleep disorders are being considered.
The main trade-off is comfort and convenience. Sleeping in a clinical room with multiple sensors attached can feel unusual, and some people find it harder to fall asleep in that setting. That said, most sleep centers work to make the environment as comfortable as possible.
Key Differences at a Glance
- Location: Home test takes place in your own bedroom; in-lab study happens at a sleep facility.
- Setup: Home devices are simple and self-applied; lab sensors are applied by a trained technologist.
- Data collected: Home tests focus on breathing and oxygen; in-lab studies capture a fuller picture of sleep activity.
- Convenience: Home tests are generally more flexible and require no overnight travel; lab studies require you to be at the facility for the night.
- Cost and coverage: Home tests are often less expensive and widely covered by insurance and Medicare when medically indicated; in-lab studies may have higher associated costs.
Which Option Might Be Right for You?
The decision isn't really one you make on your own — it's something your sleep specialist or referring provider weighs based on your symptoms and overall health picture. That said, here's a general sense of how each tends to be used:
Home sleep tests are commonly used when someone's primary concern is obstructive sleep apnea — the most frequently diagnosed sleep-related breathing disorder. They work well for adults who are otherwise in reasonably good health and whose symptoms point fairly clearly toward a breathing issue during sleep.
In-lab studies are often chosen when symptoms are more complex, when a home test hasn't given a clear answer, or when a provider wants to evaluate for conditions beyond breathing disorders — such as restless legs syndrome, parasomnias, or narcolepsy.
A Note on Telehealth Sleep Testing
Many people now begin the sleep evaluation process entirely online, connecting with a sleep specialist via a telehealth visit before ever receiving a device. This approach has made home sleep testing more accessible for people in areas where sleep clinics are limited or where scheduling an in-person visit is difficult. If you've been curious about getting tested but haven't known where to start, a telehealth consultation is often a practical first step.
Thinking About Getting Tested?
If you've been experiencing symptoms like loud snoring, waking up feeling unrefreshed, or daytime fatigue that doesn't improve with rest, a sleep evaluation may be worth exploring. A home sleep test is a convenient, non-invasive way to start gathering answers. Consider reaching out to a sleep health provider to learn whether a home sleep test might be a good fit for your situation.
