Certification of C-reactive Protein in Reference Material ERM-DA472/IFCC
The production and certification of ERM-DA472/IFCC, a new reference material certified for C-reactive protein (CRP), is described. ERM-DA472/IFCC was characterised using the reference material ERM-DA470 as calibrant. This achieved using a value transfer protocol that can be considered as a reference procedure. the principles used to measure the CRP concentration were immunonephelometry and immunoturbidimetry. The measurements were performed with different platform/reagent combinations (Abbott, Beckmann Immage, BN II, different Hitachi instruments, and Olympus AU640). In total 8 laboratories participated in the value assignment. The certified CRP mass concentration is 41.8 mg/L, the expanded uncertainty (k = 2) 2.5 mg/L.
