Which lipid test is least affected by fasting status?

Explanation:
Fasting status mainly changes the amount of postprandial triglyceride–rich lipoproteins in the blood. After a meal, chylomicrons carrying dietary fat enter circulation and trigs can spike, causing large, meal-to-meal variability. Cholesterol levels, however, don’t swing much with a single meal because they reflect longer-term hepatic synthesis and steady dietary intake rather than immediate dietary fat. So total cholesterol and related measures stay relatively stable in the short term, making cholesterol the lipid test least affected by fasting.
