Viewing the liver function test indicators is simple and is mainly a matter of comparing the measured indicator values to the range of normal values. The liver function test sheets issued by hospitals today are very intuitive, and abnormal data are marked with arrows. If the value is above the normal range, the arrow is up; if it is below the normal range, the arrow is down. Different indicators of liver function represent different clinical significance. Therefore, when liver function indicators appear abnormal, you should ask your clinician to give an analysis and judgment. The most important liver function tests are transaminases and bilirubin, especially transaminases are sensitive indicators of liver function damage. When aminotransferases are elevated, one should be alert to the possibility of liver cell damage. However, it should be noted that mild abnormalities in liver function tests are not necessarily clinically significant, and it should be ruled out whether the patient has consumed alcohol, high-fat foods or certain medications prior to the liver function test. It should also be noted that the presence of clinical disease should be further analyzed in conjunction with liver function or hepatitis B tests.
