Clinical Assessment

Category 1 (Snoring)
Category 2 (Fatigue)
Category 3 (Physical)

You scored positive in 2 or more categories. The Berlin Questionnaire indicates a high clinical probability of Obstructive Sleep Apnoea. You should discuss these results with a physician to arrange a sleep study.

You scored positive in fewer than 2 categories. This indicates a lower statistical probability of OSA, though it does not rule out other sleep disorders.
