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

The Human chorionic gonadotropin (HCG) test is considered a CLIA-waived laboratory test because it meets the criteria established under the Clinical Laboratory Improvement Amendments (CLIA) for tests that are simple to perform and have a low risk of yielding incorrect results. CLIA-waived tests can typically be performed in non-laboratory settings, such as patients' homes or physicians' offices, and do not require extensive training to administer.

The HCG test, which is commonly used to confirm pregnancy, is straightforward and often performed using urine or blood samples. Due to its simplicity and the clear guidelines provided by the manufacturer, it fits seamlessly into the CLIA-waived category.

In contrast, tests like the lipid panel and complete blood count are more complex and require higher levels of training and expertise to ensure accuracy, aligning them with more stringent CLIA classifications. The blood glucose test, while it's also often considered simple, can occasionally involve more complex methods in certain settings that may not always qualify it as CLIA-waived, depending on specifics such as the device used.
