Fasting is best: Hi. All the normal ranges for cholesterol, triglycerides, HDL, LDL, non-HDL, etc are based on fasting values. Normative values for post-challenge (i.e., non-fasting) lipids are not established. Actually, cholesterol changes very little with eating, whereas triglycerides may show a dramatic response depending on what is eaten. But yeah, do it fasting for the best info.
