Fasting Before The Test

A person will need to refrain from food and drink for 912 hours before a fasting cholesterol test.

Standard practice used to require a person to fast for 912 hours before taking a cholesterol test, meaning that they should have no food or drink other than water during that time.

However, recent guidelines have changed. They now allow doctors to recommend nonfasting cholesterol testing to certain groups of individuals.

One 2017 paper recommends nonfasting cholesterol testing, citing the following advantages of nonfasting cholesterol testing:

  • convenient
  • safe
  • no waiting required

The author also states that research involving over 300,000 people suggests that nonfasting tests are at least as accurate as fasting tests at predicting future cardiovascular health problems.

This paper suggests that the triglyceride level will rise by an average of 26 milligrams per deciliter for a nonfasting reading in comparison with the fasting level. The total cholesterol and LDL cholesterol levels will be 8 mg/dl lower, on average. The authors believe that this difference is clinically insignificant.

However, the medical community continues to debate the need for some higher-risk groups to fast before testing.

According to another analysis from the American College of Cardiology, higher-risk groups may benefit from fasting. This is because the equation that doctors use to find the LDL level tends to underestimate the levels of LDL and triglycerides in people who do not fast.
