Frequently Asked Questions from Commercial Drivers using Snap Diagnostics and Singular Sleep Program

What will happen if I do not complete my sleep test?

Once identified at-risk for sleep apnea you may be asked by your DOT Examiner to complete a sleep test to determine if you have sleep apnea. If you do not complete the sleep test your DOT Examiner may not renew your Medical Examiner’s Certificate (MEC), sometimes called a “Medical Card.” A valid MEC is required to maintain a valid Commercial Driver’s License (CDL).

Is a home sleep test accurate?

Yes. A Snap home sleep test is an excellent test. Clinical science has proven that patient outcomes when using a multi-night home test are as good or better than a sleep test performed in a sleep lab.

What if my test results are negative?

Your Snap sleep test results will be shared with your DOT Examiner. If you had a high pre-test probability of apnea your examiner may refer you to a sleep lab. Or your DOT Examiner might accept your results and renew your MEC.

What if my test results show I have sleep apnea?

Your Snap test results will be shared with your DOT Examiner and with a Board Certified Sleep Specialist at Singular Sleep, who will contact you to review options.

Does the treatment company score my sleep test? 

The answer is No! That’s a great question. The testing company, Snap Diagnostics, and the treatment company, Singular Sleep, are independent organizations. You can trust the results of the sleep test have no economic relationship to your treatment.

Will I lose my Commercial Driver’s License if I have apnea?

Many safe drivers are being treated for sleep apnea. Once you start using your treatment, a report will be provided to your DOT Examiner. Factors other than sleep apnea may impact your MEC. If you demonstrate treatment compliance and your apnea is controlled by treatment your DOT Examiner may renew your MEC.

What do I do after I complete my sleep test?

Return the Snap recorder as instructed and the test data will be analyzed by professionals trained in sleep. Your Snap sleep test results will be shared with your DOT Examiner and a Sleep Specialist at Singular Sleep. The next step will be determined by the results of the test.

What do I do if I need treatment for sleep apnea?

After your Snap Test report is released, a Singular Sleep professional will contact you to discuss the treatment options best for you. After your test report has released, you can feel free to contact Singular Sleep by phone or email using the contact information provided below.

Does the Driver have to purchase a PAP from Singular Sleep?

No. If a driver is prescribed PAP by Singular Sleep, who they elect to use for their treatment is always the choice of the driver. They can elect to purchase the PAP from a local DME or from Singular Sleep. 

If I am treated with PAP how will my DOT Examiner know if I am using my prescribed PAP treatment?

If you are prescribed PAP a report will be generated by your PAP that indicates whether you are using your treatment or not. The report will be shared with your DOT Examiner.

What if I have trouble using the recommended treatment?

Singular Sleep is committed to your success with trained professionals standing by to help. Singular Sleep is skilled in overcoming possible treatment challenges.
