Tests and diagnosis

By Mayo Clinic staff

Physical exam
Your doctor likely will perform a physical examination and take a medical history. Your partner may need to answer some questions about when and how you snore to help your doctor assess the severity of the problem. Parents are asked about the severity of a child's snoring.

Imaging
Your doctor may request an imaging test, such as an X-ray, a computerized tomography (CT) scan or magnetic resonance imaging (MRI), to check the structure of your airway for problems, such as a deviated septum.

Sleep study
Depending on the severity of your snoring and other symptoms, your doctor may also want to do a sleep study. This may require that you stay overnight at a sleep center to undergo an in-depth analysis of your sleep habits by a team of specialists, called polysomnography.

Using sensors placed on your head and various parts of your body, polysomnography records your brain waves, blood oxygen level, heart rate and breathing rate, as well as eye and leg movements during sleep.

Sometimes, these tests can be done at home, but the in-center sleep tests tend to be more accurate than those done at home.
