Clinical significance of hepatitis B two-half detection

The clinical significance of hepatitis B two-half detection lies in detecting hepatitis B virus infection, including infection status, virus replication and immunity. The results need to be judged comprehensively by multiple indicators, which is of great significance to the prevention, diagnosis and treatment of hepatitis B. Hepatitis B virus infection is the most common hepatitis B virus infection detection method in clinical practice. Its main purpose is to detect hepatitis B virus infection, determine whether hepatitis B virus infection and the type of infection. Hepatitis B two pairs of tests include hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), hepatitis B e antigen (HBeAg), hepatitis B e antibody (anti-HBe) and hepatitis B core antibody (Anti-HBc) Five indicators. The following are the clinical significance of the two pairs of hepatitis B tests: 1. Hepatitis B surface antigen (HBsAg): positive indicates infection with hepatitis B virus. HBsAg is the coat protein of hepatitis B virus, which is not infectious in itself, but its presence often indicates the presence of the virus. 2. Hepatitis B surface antibody (Anti-HBs): Positive indicates immunity to hepatitis B virus. Anti-HBs usually appears months to years after infection with hepatitis B virus and is a sign of recovery from infection or vaccination with hepatitis B vaccine. 3. Hepatitis B e antigen (HBeAg): Positive indicates active replication of hepatitis B virus and strong infectivity. HBeAg positivity is usually associated with HBV DNA positivity, suggesting that the virus replicates actively and requires further examination and treatment.(Anti-HBe): Positive indicates that hepatitis B virus replication is inhibited and infectivity is weak. Anti-HBe positive usually indicates that virus replication slows down or stops, but virus may still exist. 5. Hepatitis B core antibody (Anti-HBc): positive indicates infection with hepatitis B virus or hepatitis B virus is replicating. Anti-HBc can be divided into IgM and IgG two types, IgM anti-HBc positive indicates recent infection, IgG anti-HBc positive indicates previous infection. It should be noted that hepatitis B two pairs of test results are only preliminary judgment, and cannot be used as a basis for diagnosis of hepatitis B alone. The doctor will also combine the patient's clinical symptoms, liver function tests, hepatitis B virus DNA test results for comprehensive analysis. In addition, for hepatitis B virus infection, should be regularly reviewed, monitoring changes in the disease, timely detection and treatment of possible problems. For special groups, such as pregnant women, newborns, hemodialysis patients, hepatitis B two pairs of half detection is more important. Hepatitis B virus infection is the most common cause of hepatitis B infection. Hepatitis B virus infection is the most common cause of hepatitis B infection. Hepatitis B virus infection is the most common cause of hepatitis B infection. Hepatitis B virus infection is the most common cause of hepatitis B.
