Which type of information is least likely to be found in a CLIA-waived test package insert?

The reason the correct answer is that information about where to purchase ancillary testing supplies is least likely to be found in a CLIA-waived test package insert is that the primary focus of these inserts is on providing essential information necessary for the use and understanding of the test itself. CLIA-waived tests are designed to be simple and accessible for non-laboratory personnel, and the package insert includes critical details such as instructions for test administration, clinical indications for testing, and guidance on interpreting results.

These elements are crucial for ensuring that the tests are conducted correctly and that the results are understood within the context of patient care. In contrast, the specifics of where to obtain additional supplies are generally not included in the insert. This information may vary by location and supplier, making it less relevant to the critical use and understanding of the test as specified in the insert. Therefore, while a test package insert serves to educate healthcare providers on the aspects essential for the successful administration and interpretation of the test, it does not typically encompass commercial information such as supplier details.
