B-type natriuretic protein/N-terminal pro b-type natriuretic peptide IVD, control

B-type natriuretic protein (BNP) and N-terminal proBNP (NT-proBNP) controls are in vitro diagnostic (IVD) materials designed to validate the accuracy and reliability of assays that measure these biomarkers. Clinically, BNP and NT-proBNP are used to assess heart failure severity, monitor cardiac function, and guide treatment decisions by detecting elevated levels linked to strain on the heart.

These controls are typically regulated as IVDs and must meet performance standards to ensure they accurately simulate expected test results. They are supplied as part of quality assurance programs for laboratories, helping to confirm assay precision, linearity, and overall system integrity before patient testing begins.
