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

This category includes calibrator materials used to set reference points for laboratory tests that measure B-type natriuretic peptide (BNP) or its precursor, NT-proBNP, in patient samples. These calibrators are essential for ensuring the accuracy and consistency of immunoassays used to support the diagnosis and management of heart failure and other cardiac conditions.

As in vitro diagnostic (IVD) calibrators, these materials are regulated to ensure traceability and performance consistency across test runs and systems. They are not standalone tests but are used alongside assay reagents to calibrate measurement systems, and their supply and use are governed by IVD regulatory frameworks that require proper handling, storage, and documentation to maintain metrological traceability.
