LDTs are in vitro diagnostic products (IVDs) that the FDA has described as intended for clinical use and designed, manufactured and used within a single clinical laboratory that meets certain regulatory requirements. IVDs can play an important role in health care; they are used in the collection, preparation and examination of specimens taken from the human body, such as blood, saliva or tissue. They can be used to measure or detect substances or analytes, such as proteins, glucose, cholesterol or DNA, to provide information about a patient’s health, including to identify, monitor or determine treatment for diseases and conditions.
