What is an in-center sleep test? 

An in-center sleep test is the most detailed and thorough way to test for sleep disorders like sleep apnea. It takes place overnight in a sleep center. The patient sleeps in a private room while detailed sensors measure the patient’s brainwaves, oxygen saturation, leg motion, and other critical benchmarks. A technician oversees the patient throughout the night to ensure the most accurate results possible.

How do I schedule a sleep study? 

After your doctor refers you for a sleep study, a patient care coordinator from Advanced Sleep Medicine Services will contact you to schedule the test. Please be sure that your physician’s office has your most up-to-date contact information, such as a cell phone, work number and email (if any), so that we can reach you quickly.

If you would like us to contact your doctor to request a sleep study, you can also fill out the form below.

When will I be contacted about my sleep study?

A patient care coordinator will contact you to schedule your study once we have received the prescription (for PPO, Medicare or cash patients) or authorization (for HMO patients), your insurance information and any needed medical information (usually progress notes from your most recent office visit).

Our scheduling team is available during normal business hours Monday through Friday 8AM-6PM. You can call us during these hours at (877) 775-3377 Option 3.

When will my sleep study take place? 

Your sleep study will take place overnight in the sleep center. You will arrive at the sleep center in the evening, ready to go to bed, and you will leave in the morning by 6:00 a.m.

What do I wear to my sleep study?

Two-piece pajamas (separate top & bottom). Undergarments do not qualify as pajamas (such as men's boxers) and shorts or sleeping pants must be worn.

Even though you may have a favorite night gown or prefer to sleep au naturel, two-piece pajamas are a must for the comfort of the technician performing your study and the need to attach electrodes and leads in various positions (around your waist and legs, etc.).

Here are some examples of appropriate, two-piece pajamas to wear to a sleep study:

Can I be early/late for my appointment?

No--it is important that you arrive on time. Typically, you won't be the only person completing a sleep study in the sleep center that night. Even though you'll have a private room, the technician may have another patient that night. Setting up for the sleep study requires attaching multiple electrodes to different places on your body. This requires dedicated time and attention. If you are early or late for your appointment, this may disrupt your technician's schedule for the night and impact your study or the study of another patient. Please stick with the appointment time provided, and call us (877-775-3377 ext. 180) if you're going to arrive late.

What should I bring with me?

  • Pajamas (separate top and bottom)

  • Toothbrush and toothpaste

  • Book/magazine (to help get you settled to fall asleep or if you have to wait for a few minutes during set-up)

  • Health insurance card, driver's license or ID, and co-pay/co-insurance

  • Snack/water bottle (if you need mid-night snacks or an early feeding bring a snack bar or piece of fruit. There will be water on-site, but it's nice to have your own on-hand).

  • Pre-study paperwork. This was emailed or mailed to you after you scheduled your sleep study. You can complete the paperwork at the sleep center, but completing it beforehand will give you more time to settle in and ask your technician questions.

Can my bed partner/caregiver spend the night too?

NO, only in special cases can you bring another person to the sleep center with you. Children and patients requiring an around-the-clock caregiver MUST have someone stay with them. If needed, the sleep center will provide a cot or extra bed. 

IMPORTANT: discuss any special arrangements with the sleep center BEFORE arriving for your study. If the technician is not expecting an extra person, your study may need to be rescheduled. Please call us at (877) 775-3377 immediately if you have already scheduled your appointment and need to make special accommodations.

Will the technologist tell me the results of the study?

No, the technologist cannot give you the results of your sleep study. Each sleep study is first scored and then reviewed by an interpreting physician before a diagnosis is made. The technologist cannot provide any diagnosis or final PAP pressure, in the case of a titration study.

When will I get my results?

You will receive your results within two weeks (10 business days). Each sleep study is scored by a technician and then reviewed by a sleep specialist. See our video for more information on what happens after your sleep study.

Can I take a sleep aid or sleeping pill before my sleep study?

Our goal is to watch you sleep so that we can evaluate you for a sleep disorder. When a patient is unable to fall asleep during the evaluation, it precludes our ability to monitor their sleeping patterns. It is common for some patients to take sleeping pills to help achieve the goals of the study. 

Points to consider before taking a sleeping aid before your sleep study:

  • Continue to take any prescribed medications that you usually take (unless otherwise instructed by your doctor). If you usually take a medication at night, bring it with you to the sleep center.
  • List all medication, prescribed or over-the-counter (including any sleep aids), that you have taken, on your medication list in your intake paperwork.
  • We don’t know what effect the sleep aid may have on you, so please arrange for safe transportation home from the sleep center in the morning.
  • Generally, sleep aids have little or no effect on the diagnosis’s made from your sleep study data, but the reasons for having the sleep study need to be considered. If you are having the sleep study to evaluate sleep disordered breathing, like obstructive sleep apnea, the sleep aid shouldn’t have any effect on your normal breathing patterns. Sleep aids may change your sleep architecture like reducing the latency to sleep onset, altering the depth of sleep, changing the percentage of time spent in some sleep stages and increasing your total sleep time or sleep efficiency which could impact your diagnosis for other sleep disorders like insomnia.

It's best to talk to your doctor if you have any concerns. Most importantly, please make sure that you include the sleep aid, if you decide to take it, on your medications list.
