Sleep testing explained: home sleep tests and lab studies in Ireland.

Sleep testing means recording your physiology while you sleep so a clinician can see what is actually happening, rather than relying on how you think you slept. In practice there are two main routes: a home sleep apnoea test, and an in-laboratory sleep study.

Home sleep testing

A home sleep apnoea test focuses on breathing. A small sensor records airflow and breathing effort, oxygen levels, heart rate and body position across one night in your own bed. You set it up yourself with app guidance, sleep normally, and return the device. A clinician reviews the full recording and signs off the result.

Its advantages are practical: it is quicker to arrange, it captures a normal night in your usual environment, and there is no hospital stay. For adults whose main symptoms are snoring, witnessed pauses in breathing, or daytime sleepiness, it is an appropriate and widely used first-line test.

In-laboratory sleep studies

Polysomnography, performed overnight in a sleep unit, adds brain activity, eye movement, muscle activity and video. That extra detail is needed when the question is more complex — suspected narcolepsy, parasomnias, seizures during sleep, significant other conditions, or an inconclusive home test. It is a limited hospital resource, which is part of why waiting times exist.

How testing usually works in Ireland

Some people are referred by their GP or a consultant into a hospital sleep service. Others choose a private home test directly. With Sámh, you order online, complete a short clinical-suitability step, receive the device by post, record one night, return it, and get a phone call walking through your clinician-reviewed result and a personal recommendation on next steps.

Understanding your result

Results are usually expressed as an apnoea-hypopnoea index — the average number of breathing events per hour of sleep — alongside oxygen levels and position data. The number is interpreted with your symptoms rather than on its own, and it guides whether next steps are positional and lifestyle changes, a dental device, CPAP, or referral for further assessment.

Which route to choose

If snoring and breathing are the concern, start with a home sleep test. If your symptoms suggest something other than sleep-disordered breathing, or a home test has already been inconclusive, a laboratory study through a sleep service is the right path. Either way, testing is more useful than waiting to see whether it settles.
