Remarks Measurement of lipids and lipoproteins is primarily used to estimate the risk of atherosclerotic cardiovascular disease and guide therapeutic decision-making (ESC/EAS 2019), and as part of the identification and management of patients with familial hypercholesterolaemia (NICE CG71). The Lipid Programme includes all routinely monitored analytes for the screening, diagnosis and management of dyslipidaemias by the clinical laboratory, covering all the measured and calculated parameters. Forty frozen endogenous (single or pooled) human serum samples and eight fresh single donor samples are distributed annually. Reference target values using a CRML laboratory is provided for TC, TG, and HDL-C. A wide clinically relevant range is distributed, along with samples with high TG concentration to challenge the TC and LDL-C methods. The programme assesses both laboratory and method performance, including bias, within and between batch imprecision. Trueness is also assessed for a number of analytes using high metrological order Reference measurement systems. A less rigorous separate programme is provided for POCT sites undertaking healthcare screening. Key Features: - Liquid human serum samples requiring no prior preparation. - Commutable single and pooled donor samples. - Lipid profile includes all routinely monitored analytes and calculated parameters. - Traceable IDGCMS and CDC reference values provided for Cholesterol, Triglyceride and HDL. - Sigma metric scoring based on clinically relevant Milan Model 2 performance specification.
