A certified reference material is a material which has been certified by some trusted organisation to be of a consistent quality and composition. Normally, but not always, the concentrations of the major components of a CRM have been carefully measured.

NOTE 2 Procedures for the production and certification of certified reference materials are given, e.g. in ISO Guide 34 and ISO Guide 35. NOTE 3 In this definition, "uncertainty" covers both 'measurement uncertainty' and 'uncertainty associated with the value of a nominal property ', such as for identity and sequence.

9/22 · While Reference Materials do not give the same level of accuracy as Certified Reference Materials, their advantage is that they are significantly easier to produce. They are

Presently, there is no agreement on what kind of BNP or NT-proBNP standard should be used for calibration, and a certified reference material as well as reference measurement procedures are lacking. The aim of this chapter is to summarize the available data on the complex nature of BNP-related peptides, specificity for existing BNP and NT

As per ISO 17034, certified reference materials are defined as "sufficiently homogenous and stable with respect to one or more specified properties (qualitative or quantitative) which have been established to be fit for its intended use in a measurement process." A CRM is distinguished and identified by a certificate that demonstrates not

Reference material accompanied by a certificate, one or more of whose property values are certified by a procedure which establishes its traceability to an accurate realisation of the unit in which the property values are expressed, and for which each certified value is accompanied by an uncertainty at a stated level of confidence.

With the Certified Reference Material (CRM) or Reference Material grade comes the Certificate of Analysis (CoA). Within the CoA, there are several quality parameters which are critical to understand: accuracy, consistency, homogeneity, purity, and stability. Also, what is being certified is important to understand – namely, the certified
