The Evolution and Future of Point-of-Care Testing

Regulatory Approach to Point-of-Care/At-Home Testing in the United States

The Clinical Laboratory Improvement Amendments (CLIA) classifications were activated in the 1990s in partnership with the Centers for Medicare and Medicaid Services and Food and Drug Administration and included waived, moderate, and high complexity testing. The waived section of CLIA certificates allows laboratories to perform testing of analytes and methods of samples by the Food and Drug Administration. During the COVID-19 pandemic, many molecular or antigen laboratory testing methods for COVID-19 virus were quickly approved by emergency use authorization. Waived testing is now done in highly complex, moderately complex, and waived testing laboratories, and some at-home testing.
