[Comparison of calculated LDL cholesterol (LDL-C) versus measured LDL cholesterol (LDL-M) and potential impact in terms of therapeutic management].

LDL-cholesterol value is one of the criteria used by the Haute autorité de santé (HAS) in the management of patients in primary and secondary prevention with the aim to reduce cardiovascular mortality. In this respect, the recommendations have been established based on target to achieve LDL-cholesterol. Currently in France, the determination of LDL-cholesterol is mainly carried out by the Friedewald formula whose limits are well known.
