What is the liver function test for onboarding physical examination

The liver function examination during the onboarding physical examination mainly includes indicators such as alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin, albumin, etc., which are used to evaluate liver metabolism, synthesis, and detoxification function.

1. Aspartate transaminase

Aspartate transaminase mainly exists in liver cells and is a sensitive indicator reflecting liver cell damage. The increase in numerical values may be related to factors such as viral hepatitis, fatty liver, and drug-induced liver injury. Mild elevation can be improved by adjusting daily routine and diet, while significant elevation requires further examination to determine the cause.

2. Aspartate transaminase

Aspartate transaminase is distributed in liver and myocardial cells, and an abnormal increase in its value may indicate liver or heart disease. Long term alcohol consumption, cirrhosis, and other factors can lead to an increase in this indicator, and further diagnosis should be made in conjunction with imaging examinations.

3. Total bilirubin

Total bilirubin reflects bile metabolism, including direct and indirect bilirubin. An increase in numerical value may be caused by biliary obstruction, hemolytic disease, or genetic jaundice. Mild elevation may be related to staying up late or drinking alcohol, and persistent abnormalities require screening for liver and gallbladder diseases.

4. Direct bilirubin

Elevated direct bilirubin usually indicates bile excretion disorders, commonly seen in diseases such as bile duct stones and cholangitis. Abnormal indicators may be accompanied by symptoms such as skin itching and clay colored feces, and the cause needs to be confirmed through ultrasound or CT examination.

5. Albumin

Albumin is synthesized by the liver, and a decrease in its value may reflect chronic liver disease, malnutrition, or renal dysfunction. Long term hypoalbuminemia can lead to edema, which needs to be judged comprehensively based on other liver function indicators and urine routine. Individuals with abnormal liver function should avoid drinking alcohol and high-fat diets to ensure adequate sleep. Mild abnormalities in indicators can be rechecked 1-3 months later. If the abnormalities persist or are accompanied by symptoms such as fatigue and jaundice, it is recommended to seek medical attention from a gastroenterologist to complete hepatitis virus screening, liver ultrasound, and other examinations. Daily intake of foods rich in vitamin B, such as whole grains and green leafy vegetables, can help with liver repair.
