Do you need to fast before cholesterol lab?

No…  but, occasionally yes. 

A study of over 209,000 cholesterol labs found that if we are only looking at total cholesterol and LDL (bad) cholesterol, that patients do NOT need to fast. 

The triglycerides (another part of the cholesterol/lipid panel) will be elevated by less than 20% if taken nonfasting compared to fasting.

So, this means, that unless I am concerned about high triglycerides, the patient can have lab drawn conveniently during an office appointment regardless of timing of last meal.
