What are the laboratory indicators for determining hepatitis

The determination of hepatitis requires a comprehensive analysis of multiple laboratory indicators, mainly including liver function indicators, hepatitis virus markers, blood and urine routine, coagulation function indicators, imaging auxiliary indicators, etc.

1. Liver function indicators: Alanine transaminase (ALT) and aspartate transaminase (AST) are sensitive indicators reflecting liver cell damage. ALT often significantly increases in acute hepatitis, while it may continue to slightly increase in chronic hepatitis. Elevated bilirubin (total bilirubin, direct bilirubin) indicates abnormal bile metabolism, while decreased albumin may reflect a decline in synthesis function caused by chronic liver disease.

2. Hepatitis virus marker: positive hepatitis B B surface antigen (HBsAg) indicates hepatitis B virus infection, while positive hepatitis C antibody (anti HCV) indicates hepatitis C virus infection. Virus nucleic acid testing (such as HBV-DNA, HCV-RNA) can further confirm the replication status of the virus and guide antiviral treatment.

3. Blood and urine routine tests: In the early stage of acute hepatitis, the total number of white blood cells may be normal or slightly higher, and lymphocytes may increase relatively during the jaundice stage; Positive urine bilirubin and urobilinogen in urine routine can help distinguish the type of jaundice, and both are positive in hepatocellular jaundice.

4. Coagulation function indicators: Prolonged prothrombin time (PT) for more than 3 seconds indicates severe liver cell damage, while an increase in international normalized ratio (INR) indicates the risk of liver failure.

5. Imaging auxiliary indicators: Abdominal ultrasound can observe changes in liver morphology and detect structural abnormalities such as fatty liver and cirrhosis; Transient elastography of the liver can non invasively evaluate liver stiffness and assist in determining the degree of fibrosis. The diagnosis of hepatitis requires a comprehensive analysis of multiple laboratory indicators and clinical manifestations. If symptoms such as fatigue and jaundice occur, it is necessary to seek medical attention promptly and undergo a comprehensive examination. If accompanied by liver fibrosis after diagnosis, it is recommended to use Fuzheng Huayu Capsules according to medical advice. It can regulate the liver microenvironment, inhibit fibrosis development, improve liver function, and reduce the risk of disease deterioration.
