What is a CLIA waiver?

If your facility runs even a simple drug screen on site, this is the certificate that makes it legal. Here's what it is, who needs one, and how to get it.

A CLIA waiver — formally a Certificate of Waiver — is a federal certificate, issued under the Clinical Laboratory Improvement Amendments (CLIA), that lets a facility perform simple, low-risk lab tests classified as "waived," such as urine drug screens and rapid point-of-care tests. Any facility that tests samples on site — including behavioral health and addiction treatment programs — needs one to do so legally.

What "waived" actually means

The FDA sorts lab tests by complexity. "Waived" tests are the simplest category — tests with such a low risk of error that they're exempt from the more intensive requirements that apply to complex lab work. A Certificate of Waiver covers exactly these tests. The most common one in behavioral health is the on-site urine drug screen.

Who needs one

The test is simple: do you test samples on your own premises? If a urine sample is read at your facility — even with a simple dip cup — rather than shipped to an outside lab, you're operating a laboratory in the eyes of CMS and need at least a Certificate of Waiver. Behavioral health programs, addiction treatment facilities, and clinics running their own screens all fall under this.

How to apply

  1. Confirm your tests are waived

    Verify the specific tests you'll run are in the waived category. Anything more complex needs a higher certificate level.

  2. Complete CMS Form 116

    The CLIA application. Accuracy here is what determines whether you're approved in weeks or stuck in correction loops.

  3. Submit & pay

    File with the appropriate state agency (in California, Laboratory Field Services) and pay the certificate fee.

  4. Receive your certificate

    Once approved, CMS issues a Certificate of Waiver valid for two years, after which you renew.
