Why is fasting necessary for liver function panel testing?

Fasting is an essential step before undergoing a liver function panel test. This test measures enzymes, proteins, and substances produced or processed by the liver, helping assess its overall health and functionality. Fasting, usually for 8 to 12 hours, ensures accurate results by eliminating variables that could alter the blood chemistry.

When we eat, our body metabolizes food, and this affects the levels of glucose, lipids, and certain enzymes in the blood. These temporary fluctuations can interfere with liver panel results, potentially leading to misinterpretation. For example, certain foods can elevate liver enzymes or bilirubin levels, giving a false indication of liver dysfunction. Fasting helps maintain a stable baseline, offering a true picture of the liver’s condition.

Fasting also reduces the risk of lipemia—a condition where excess fats in the blood make it appear cloudy. This can interfere with the laboratory’s ability to analyze the blood sample accurately, especially in tests involving albumin and total protein.
