Which of the following best describes the focus of waived tests?

Waived tests are defined by their simplicity and low risk—meaning they can be performed without extensive training or complex laboratory equipment. The primary goal of waived tests is to ensure accessibility to basic testing that can be accurately conducted by individuals who may not have specialized training, as they do not involve complicated procedures or techniques that could pose significant safety concerns.

Choosing this option aligns with the guidelines established by the Clinical Laboratory Improvement Amendments (CLIA), which categorize tests based on the level of complexity, and waived tests fall into the "minimal risk" category. This ensures that even non-professionals can safely administer them, making healthcare more accessible while maintaining patient safety.

In contrast, the other options describe characteristics of tests that generally have higher levels of complexity or risk, which do not fit the definition of waived tests.
