C-reactive protein (CRP) IVD, control

C-reactive protein (CRP) IVD controls are laboratory materials designed to ensure the accuracy and reliability of tests that measure CRP levels in patient samples. These controls help validate whether an assay—whether standard or high-sensitivity (hsCRP)—is functioning correctly, reducing the risk of false results in diagnosing inflammation, infection, or cardiovascular risk.

These controls are typically regulated as in vitro diagnostics (IVDs) and must meet performance standards to ensure clinical validity. They are supplied as part of assay kits or as standalone reagents, often categorized by concentration ranges to assess different levels of CRP detection. Compliance with regulatory requirements varies by jurisdiction, but all must demonstrate precision and accuracy in controlled testing environments.
