Regulation of Clinical Tests: In Vitro Diagnostic (IVD) Devices, Laboratory Developed Tests (LDTs), and Genetic Tests

Summary

In vitro diagnostic (IVD) devices are used in the analysis of human samples, such as blood or tissue, to provide information in making health care decisions. Examples of IVDs include pregnancy test kits or blood glucose tests for home use; laboratory tests for infectious disease, such as HIV or hepatitis, and routine blood tests, such as cholesterol and anemia; and tests for various genetic diseases or conditions. More recently, a specific type of diagnostic test--called a companion diagnostic--has been developed that may be used to select the best therapy, at the right dose, at the correct time for a particular patient; this is often referred to as personalized or precision medicine. This report provides an overview of federal regulation of IVDs by FDA, through the Federal Food, Drug, and Cosmetics Act (FFDCA) and the Public Health Service Act (PHSA), and by CMS, through the Clinical Laboratory Improvement Amendments (CLIA) of 1988.
