A patient fasting since midnight has a lipid panel collected at 7 am. Which test should be recollected?

Explanation:
Triglyceride levels are heavily influenced by recent food intake because after eating the gut packages fats into chylomicrons that raise blood triglycerides. To get an accurate fasting triglyceride measurement, a prolonged fast of about 9–12 hours is recommended. In this case, seven hours of fasting is not enough, so the triglyceride result could be falsely elevated and should be recollected after the patient has completed a full fasting period. The other measurements listed are not dependent on a strict fasting window in the same way, so recollection isn’t necessary for them to interpret the lipid panel.
