The sleep study test kit is great for detecting obstructive sleep apnea, but not for central apneas, which you may have. That needs an overnight sleep study. If the test kit does not detect obstructive sleep apnea ask your family doctor for a referral directly to an in‑lab sleep study (polysomnography) Tell your doctor "I’m concerned about possible central sleep apnea. Home sleep tests often miss central events, so I’d like a referral for an in‑lab overnight polysomnography."

Keep in mind that you may not have any apneas at all. There may be some other cause. No matter the cause, you do need help. May you find the help you need. Good luck.
