General description

LNE CRM Bio 101L1 is a JCTLM database listed, higher-order certified reference material produced by the French metrological institute LNE in compliance with ISO 17034 requirements. This secondary standard is intended for use as quality control material to assess the measurement bias or measurement uncertainty of established or new measurement procedures for the determination of creatinine, glucose, total cholesterol, total glycerides, HDL-cholesterol and LDL-cholesterol in human serum. The Certified Reference Materials LNE CRM Bio 101L1 and LNE CRM Bio 101L2 correspond to 2 pools of Human Frozen Serum that were prepared according to the Clinical Laboratory Standards Institute (CLSI) C37-A guidelines describing the preparation and validation of commutable frozen human serum pools as Secondary Reference Materials for Cholesterol Measurement. Samples commutability was assessed through 2 commutability studies according to the difference in bias approach described in the IFCC recommendations on commutability assessment involving several clinical laboratories. Commutability results are reported in the certificate of analysis.
