How to Interpret a Liver Function Test Report?

Liver function test report mainly focuses on whether there is any problem with transaminase, that is, whether liver cells are damaged. Bilirubin mainly reflects the liver's ability of transformation and metabolism. Another aspect is the plasma protein index, which indicates the protein level and whether the liver's synthetic ability is affected. From a clinical perspective, there is no need to worry if the test results are within the normal range.

1. Bilirubin metabolism index

Bilirubin metabolism index can be found in the liver function test report, mainly focusing on bilirubin metabolism indicators. Common bilirubin metabolism test items include: serum total bilirubin (TBil), serum direct bilirubin (DBil), and serum indirect bilirubin (IBil). The bilirubin index in serum is mainly used to determine the type and degree of jaundice, and further to judge whether liver metabolism is normal.

2. Plasma protein index

Bilirubin metabolism index is generally based on plasma protein, which can also be found in the liver function test report. The liver is the main organ of protein metabolism in the body. Proteins such as albumin, lipoproteins, coagulation factors, fibrinolytic factors, and various transport proteins are synthesized by liver cells. When liver function is impaired, these proteins decrease; in case of inflammation, γ-globulin may increase. Measuring serum protein levels can help understand the liver's metabolic function of proteins.
