CLIA-waived tests are defined as tests that provide simple, unvarying results and require a minimum amount of judgment and interpretation.

• A. Tests that require specialized equipment and extensive interpretation
• B. Tests that provide simple, unvarying results and require minimal judgment and interpretation
• C. Tests that measure only post-analytic results
• D. Tests that are only performed in high-complexity laboratories

Answer: (B)

CLIA-waived tests are defined by their simplicity and low potential for error. They provide straightforward, consistent results and require minimal judgment or interpretation to determine what the result means. This makes them safe to use outside specialized laboratories and suitable for quick, point-of-care decisions in clinics or other non-lab settings. That’s why the description of producing simple, unvarying results and needing little interpretation best matches the concept.

Think of common examples like urine dipsticks, simple pregnancy tests, and glucose meters—these are designed to be easy to perform and interpret with minimal training. In contrast, tests that need specialized equipment and extensive interpretation are categorized as higher complexity and do not fit the waived criteria. Likewise, a test that measures only post-analytic results or is restricted to high-complexity labs wouldn’t be described as CLIA-waived.
