Fasting blood samples have been the standard for measurement of
triglycerides and cholesterol, despite the fact that we spend the vast
majority of our time in non-fasting conditions. However, when recent
studies suggest that postprandial effects do not substantially alter
lipid concentrations and do not weaken, and even may strengthen, their
association with cardiovascular risk, then a non-fasting blood draw has
many practical advantages. Non-fasting cholesterol measurements include
the ‘remnant cholesterol’ fraction, a strong risk factor for developing
atherosclerosis independent of LDL cholesterol. Remnant cholesterol
reflects the cholesterol in chylomicron- and VLDL-remnant particles and
it is included in the ‘non-HDL cholesterol’ calculation.
Until recently, most guidelines focused on targeting primarily LDL cholesterol for the prevention of cardiovascular disease, but they now recognize that non-HDL cholesterol (or apolipoprotein B, the molecule carried by all non-HDL particles) is a more accurate and comprehensive predictor of atherogenic lipoprotein-related risk.
In 2016, the European Atherosclerosis Society (EAS) and EFLM Joint Consensus Panel recommended using non-fasting lipid testing for routine clinical practice and provided specific cutpoints for desirable fasting and non-fasting lipid concentrations to be reported by the laboratories uniformly.
