What Is a Home Sleep Test? How Is It Different from a Hospital Sleep Study

How many types of sleep tests are there

A full, standard sleep test (Sleep Test) is usually done at a hospital or sleep center, staying overnight with multiple monitoring points attached (brain waves, breathing, blood oxygen, movement, etc.) to get the most detailed data possible.

A Home Sleep Test (HSAT) is an alternative that uses a portable device, measuring key values such as breathing and blood oxygen, while sleeping normally at your own home.

Who is a home test suitable for

A home test is generally suitable for people a doctor has assessed as having moderate to high sleep apnea risk, without complex co-existing conditions that require a full hospital-based test. Deciding which method is appropriate should be a doctor's judgment after an initial assessment.

Advantages and limitations

The advantage of a home test is convenience, sleeping in a familiar environment, and usually lower cost than an overnight hospital stay. The limitation is that it measures fewer variables than a full test, so it may not be suitable for people with complex symptoms or suspected other sleep disorders alongside it.

Whichever test you take, the recommended first step is to consult a doctor for an initial assessment. A preliminary risk screening like STOP-BANG makes it easier to decide whether to book a doctor's appointment for further testing.
