In Vitro Diagnostic (IVD) Device
In Vitro Diagnostic device: a test, reagent, instrument, or system used to examine specimens like blood or tissue outside the body to detect disease or guide treatment. IVDs are regulated as medical devices and span lab analyzers to point-of-care kits.
What is an In Vitro Diagnostic (IVD) Device?
An In Vitro Diagnostic (IVD) device is a test, reagent, instrument, or system used to examine specimens taken from the body, such as blood, urine, or tissue, outside the body itself. The term in vitro means the analysis takes place in a controlled setting like a laboratory or testing cartridge rather than within the patient.
IVDs range widely, from large automated laboratory analyzers to compact point-of-care kits used at the bedside. Because they produce information that guides medical decisions, they are regulated as medical devices.
Why are In Vitro Diagnostic devices important?
IVDs supply much of the objective data that clinicians rely on to detect disease, confirm diagnoses, and decide on treatment. Their accuracy and reliability directly affect the quality of the decisions made from their results.
Their regulation as medical devices reflects the consequences of error: a faulty test can lead to a missed diagnosis or inappropriate therapy. As a result, IVDs are subject to validation and quality requirements appropriate to their clinical risk.
