You can get a sleep apnea test at an accredited sleep center, through your primary care doctor’s office with a home test kit, or through online telehealth services that ship a testing device to your door. The right option depends on your symptoms, insurance coverage, and whether your doctor suspects other sleep disorders beyond apnea.
Home Sleep Tests
Home sleep apnea tests are the most convenient and affordable option for most people. You wear a small portable device while sleeping in your own bed, typically for one or two nights. The device records your breathing patterns, blood oxygen levels, heart rate, and chest movement. In the morning, you return or mail back the device, and a sleep specialist reviews the data.
These kits generally cost between $660 and $770 for the testing portion alone, compared to roughly $1,000 to $1,125 for an in-lab study. Many insurance plans cover home testing when a doctor orders it, which can bring your out-of-pocket cost down significantly. Companies like Lofta ship FDA-approved wrist-worn devices directly to your home that include a finger probe and chest sensor.
The trade-off is accuracy. A meta-analysis of 59 studies found that portable home devices correctly identified sleep apnea about 93% of the time at the mildest threshold, but that sensitivity dropped to 79% for detecting moderate and severe cases when used at home. The devices also had a higher technical failure rate at home compared to being used in a supervised lab setting. If your home test comes back normal but you still have symptoms like loud snoring, gasping during sleep, or daytime exhaustion, your doctor will likely recommend a full lab study.
In-Lab Sleep Studies
An overnight sleep study at a sleep center, called polysomnography, is the most thorough option. You spend a night at a specialized facility where technicians attach sensors that track your brain waves, eye movements, muscle activity, heart rhythm, breathing effort, airflow, and oxygen levels. This is the gold standard test, and it’s the only option if your doctor suspects you have a condition beyond obstructive sleep apnea, such as central sleep apnea, narcolepsy, or periodic limb movement disorder.
Lab-based testing is notably more accurate across every severity level. At the threshold for moderate sleep apnea (15 or more breathing disruptions per hour), lab studies had 92% sensitivity and 91% specificity, compared to 79% and 79% for home devices. For severe cases, lab accuracy climbed to 97% sensitivity and 93% specificity.
To find an accredited sleep center near you, use the American Academy of Sleep Medicine’s directory at sleepeducation.com/find-a-center. You can also verify a center’s accreditation by contacting the AASM directly. The American Board of Sleep Medicine maintains a searchable list of board-certified sleep specialists if you want to confirm your doctor’s credentials.
Telehealth Services
Several online platforms now bundle virtual consultations with home sleep testing. You complete an intake questionnaire, have a video visit with a sleep specialist, and receive a home test kit by mail. If your results confirm sleep apnea, some of these services can also prescribe treatment equipment through the same platform. This route works well if you don’t have a primary care doctor, live in a rural area, or want to skip the in-person appointment.
Keep in mind that telehealth services still require a licensed physician to review your case and order the test. You’re not bypassing the medical system, just accessing it remotely.
Do You Need a Doctor’s Referral?
Yes. Both home and lab-based sleep tests require an order from a physician or qualified healthcare provider. You cannot walk into a sleep center or order a clinical-grade home test without one. Your primary care doctor, an ENT specialist, or a pulmonologist can all place this order. If your insurance requires prior authorization, your doctor’s office typically handles that paperwork.
For insurance coverage, Medicare and most private plans require documentation showing medical necessity. This usually means your doctor needs to note symptoms like observed apnea episodes, excessive daytime sleepiness, or loud habitual snoring in your medical record. The ordering physician’s information must appear on the claim, and the medical notes need to support the diagnosis code.
Understanding Your Results
Sleep apnea severity is measured by the apnea-hypopnea index, or AHI, which counts how many times your breathing partially or fully stops per hour of sleep. The standard categories for adults are:
- Mild: 5 to fewer than 15 events per hour
- Moderate: 15 to fewer than 30 events per hour
- Severe: 30 or more events per hour
An AHI below 5 is considered normal. Your treatment options depend heavily on where you fall on this scale. Mild cases might be managed with positional therapy or a dental appliance (the American Academy of Dental Sleep Medicine has a directory of dentists who specialize in these devices at aadsm.org). Moderate to severe cases typically call for a CPAP machine. If your home test places you in a borderline range or the results seem inconsistent with your symptoms, your doctor may order a follow-up lab study to get a clearer picture.
Which Option Is Right for You
If you’re an adult with classic symptoms of obstructive sleep apnea, such as snoring, witnessed breathing pauses, and daytime sleepiness, a home test is a reasonable and cost-effective first step. The total cost of a home-based diagnostic pathway averages around $1,575, compared to $1,840 for the lab-based route when you factor in all associated visits and follow-ups.
A lab study is the better choice if you have significant heart or lung disease, if your doctor suspects a sleep disorder other than obstructive apnea, or if a previous home test was inconclusive. It’s also preferred for children, since home devices aren’t validated for pediatric use. Some insurance plans require a home test first and only cover a lab study if the home results are unclear, so checking your specific coverage before scheduling can save you time and money.
