Which of the following is considered a CLIA-waived laboratory test?

The choice of the fecal leukocyte test as a CLIA-waived laboratory test is accurate based on the criteria set forth by the Clinical Laboratory Improvement Amendments (CLIA). CLIA-waived tests are those that are simple and have a low risk of incorrect results. They can be performed in a variety of settings, including clinics and doctors' offices, without the need for complex laboratory equipment or specialized training.

The fecal leukocyte test, which is used primarily to detect the presence of white blood cells in stool samples, is considered straightforward and easy to interpret. It plays a crucial role in diagnosing bacterial infections in the intestines. Since the test's performance is not overly complicated and the interpretation of results does not require extensive laboratory infrastructure, it fits the definition of a CLIA-waived test.

In contrast, tests such as a complete blood count, cholesterol test, and throat culture typically require more complex procedures, sophisticated equipment, or interpretation by trained laboratory personnel, which places them outside the scope of CLIA-waived tests. Each of these tests involves multiple steps or significant laboratory processing that necessitates more stringent oversight to ensure accuracy and reliability.
