Sleep Study Options
A sleep study tracks what happens while you sleep to help identify problems like sleep apnoea. There are four levels, ranging from simple home tests to full overnight studies in a clinic.
Level 1
A Level 1 sleep study is the gold standard of sleep testing. It’s an overnight stay in a specialised sleep clinic where your breathing, brain waves, heart rate, and movements are closely monitored to get the most accurate picture of your sleep health.
Level 2
Designed for home use, this test captures the same detailed data as an in-lab study. It measures brain waves, breathing effort, oxygen levels, heart rate, and other vital signs to provide a full clinical picture without needing a hospital stay.
Level 3
This simplified home test focuses on key signals like airflow, breathing effort, oxygen levels, and heart rate. It’s a practical option for people with a high likelihood of sleep apnoea, offering convenience and clinical usefulness.
Level 4
Ideal for quick screening, this test tracks one or two basic signals such as oxygen levels and pulse rate while you sleep at home. It’s useful for spotting moderate to severe sleep apnoea in people who are likely to have the condition.
