What is the purpose of CLIA '88?

To standardize reagents globally

To improve the accuracy of laboratory testing regardless of where tests are performed.

CLIA '88 creates nationwide standards to ensure that laboratory tests are accurate and reliable no matter where they’re performed. It brings uniform quality controls, personnel qualifications, proficiency testing, and inspections to all clinical labs, so a test run in a hospital, clinic, or independent lab meets the same basic level of quality. This focus on consistency and reliability helps protect patients from erroneous results that could occur if different places used different practices.

It’s not about standardizing reagents globally, nor privatizing laboratory testing, and it doesn’t certify only high-complexity labs—the framework applies across testing settings with categories based on complexity, including waived tests.
