Do you know where your at-home lab test samples are processed?

The answer: in a CLIA-certified lab.

But that doesn’t tell you much.

This article explains what a CLIA-certified lab is and why your samples must be processed in one.

But first, what does CLIA stand for?

CLIA stands for the Clinical Laboratory Improvement Amendments.

These are a set of regulations implemented by the U.S. government in 1988. They apply to all U.S. facilities or sites that test human specimens for health assessment or to diagnose, prevent, or treat disease. 

CLIA regulations set quality standards to ensure you receive accurate, reliable, and timely test results. A CLIA-certified lab meets these stringent standards and operates under a specific CLIA certificate based on test complexity.

The Centers for Medicare & Medicaid Services (CMS) issue these certificates. And the labs must renew them every two years after undergoing a rigorous inspection.

What Are the Different Types of CLIA Certificates?

There are five types of CLIA certificates. Each one is related to the complexity of the tests a lab performs:

  1. Certificate of Waiver (CoW)– issued to labs that only perform tests categorized as “waived” due to their simplicity and low risk of error
  2. Certificate for Provider-Performed Microscopy Procedures (PPMP)– for labs in which a physician, midlevel practitioner, or dentist performs no tests other than the microscopy procedures (and waived tests)
  3. Certificate of Compliance (CoC)– for labs demonstrating compliance with all CLIA standards during an onsite survey
  4. Certificate of Accreditation (CoA)– For labs accredited by CMS-approved organizations, which ensure these labs meet or exceed CLIA standards
  5. Certificate of Registration (CoR)– for labs that have registered but have yet to be surveyed or have yet to declare a specialty/subspecialty for the CMS to determine the applicable requirements

Why Should Samples Be Analyzed In A CLIA-Certified Lab?

Accuracy. You want results you can trust when you take any health and wellness test. A CLIA-certified lab must follow precise, standardized procedures in handling and analyzing samples. This precision minimizes the risk of errors and helps produce consistently accurate results.

High-quality standards. CLIA-certified laboratories must employ qualified personnel who meet educational and experiential prerequisites. Moreover, the labs need to take part in proficiency testing – a system where unknown samples are sent to labs to ensure they can produce accurate and reliable results. If a lab fails this testing, they can lose their certification.

Oversight and accountability. Certified labs are subject to routine inspections to guarantee continuous compliance with CLIA standards. If issues arise during these inspections, labs must address and rectify them, ensuring they uphold the best practices in the field.

Protects patients’ rights. As part of the certification process, labs must adhere to the Health Insurance Portability and Accountability Act (HIPAA), which protects patient data privacy and confidentiality. This is crucial when you’re sharing personal health information for at-home testing.
