Home Sleep Tests

There are many different “levels” of sleep tests available these days. Each different level varies in terms of the quality of test and the amount of information obtained. The best available is a Level-1 study study (in a sleep centre with trained sleep technologists). The highest quality home sleep test available is a Level-2, and they then range down to a level-4 test. 

The best way to think about a home sleep test is it being a tool for screening moderate-to-severe Obstructive Sleep Apnea (OSA). Doctors do not commonly rely on a home sleep test to be accurate for less severe OSA or diagnosing other sleep disorders. 

 

The most common home sleep test, typically performed by pharmacies, is a Level-3 study which has very limited channels for recording EEG, focusing mainly on breathing and oxygen levels. Level-4 studies typically only record breathing and oxygen saturation. These limited channel home sleep tests tend to dramatically under-diagnose sleep disorders and have a relatively high failure rate.

Sleep Health Group only offer the highest level of home sleep testing (Level-2), measuring EEG, EOG, EMG, leg movements, effort of breathing, nasal airflow, snoring, ECG and oxygen levels. However, the home sleep test is not for everyone. If you are suspected of having moderate-to-severe OSA, then a home sleep test may be appropriate for confirming this diagnosis.

 

If your severity of OSA is predicted to be lower than this, if you are being investigated for any other sleep disorder or if you have a complex medical history, then a home sleep test is often not appropriate and an attended Level -1 sleep study should be recommended.
