Categorization of Tests

Since November 13, 2003, the Food and Drug Administration (FDA) has had the authority to implement the Clinical Laboratory Improvement Amendments (CLIA) test complexity categorization provisions, which includes, but is not limited to the following:

  • Interpreting the CLIA provisions related to complexity categorization;
  • Holding public workshops and meetings on CLIA complexity categorization; and,
  • Developing and issuing implementing rules and guidance for CLIA complexity categorization.

Refer to the link below to access the FDA CLIA database containing the commercially marketed in vitro test systems categorized by the FDA since January 31, 2000 and the tests categorized by the Centers for Disease Control and Prevention prior to that date.

The following information appears as a download below:
