Full blood count IVD, control

Full blood count (FBC) in vitro diagnostics (IVDs) controls are reference materials designed to ensure the accuracy and reliability of blood tests that measure key cell parameters like red blood cells, white blood cells, platelets, and other markers. Clinically, these controls help laboratories validate their testing systems for complete blood count (CBC) assays, ensuring consistent and trustworthy diagnostic results for patient care.

These controls are typically regulated as IVDs and may be classified differently depending on jurisdiction, though they are not medical devices for direct patient use. They are supplied as ready-to-use liquids or lyophilized formats, often with expiration dates and stability guidelines, to support routine quality assurance in clinical laboratories.
