You may be referred to a sleep specialist for a variety of reasons, including sleep apnea, insomnia, and more. If you are being referred on suspicion of having sleep apnea, Peak and its sister company, Peak Sleep Clinic, offer FREE take-home overnight sleep apnea testing for patients who believe they suffer from Sleep Apnea.

Sleep Apnea is a condition where a person’s breathing is interrupted during sleep. Those with severe sleep apnea can have these episodes hundreds of times a night, meaning that they are not getting enough oxygen.

Signs you may have Sleep Apnea:

  • Snoring
  • Gasping/choking while sleeping
  • Daytime fatigue
  • Poor concentraion
  • Memory issues
  • High blood pressure


A referral is not necessary but is recommended for Sleep Apnea testing. There are numerous Peak Sleep Clinics that you can go to to pick up your FREE test. If you are diagnosed with Sleep Apnea, Peak Sleep Clinic also offers CPAP trials and purchases as well as accessories such as masks, hoses, filters and more. Learn more at
