What items are checked for hepatitis B?
Hepatitis B is a liver disease caused by the hepatitis B virus (HBV), and early detection and treatment are crucial to preventing cirrhosis and liver cancer. Hepatitis B testing involves many items. The following is the content related to hepatitis B testing that has been hotly discussed on the Internet in the past 10 days, and is structured data compiled based on medical guidelines.
1. Core items of hepatitis B examination
Hepatitis B testing usually includes testing for viral markers, liver function assessment, and imaging studies. The following are common inspection items and their significance:
| Check items | English abbreviation | clinical significance |
|---|---|---|
| Hepatitis B surface antigen | HBsAg | Core indicator to determine whether you are infected with HBV. Positive indicates current infection. |
| Hepatitis B surface antibody | HBsAb | Positive indicates immunity to hepatitis B virus (after vaccination or recovery) |
| Hepatitis B e antigen | HBsA | Reflects the activity of virus replication, and a positive indicates high infectivity |
| Hepatitis B e antibody | HB | Positive may indicate weakened viral replication, but needs to be combined with other indicators |
| Hepatitis B core antibody | HBcAb | Distinguish between past infection and current infection (need to be combined with HBsAg) |
| HBV-DNA quantification | HBV-DNA | Directly detect viral load to assess infectivity and treatment efficacy |
2. Liver function related tests
Hepatitis B patients need to regularly monitor liver function. The following are key indicators:
| Project | normal range | abnormal meaning |
|---|---|---|
| alanine aminotransferase | 0-40U/L | Elevated levels indicate liver cell damage |
| aspartate aminotransferase | 0-35U/L | Combined with ALT to determine the degree of liver damage |
| total bilirubin | 3.4-20.5 μmol/L | Elevated levels may indicate cholestasis or hemolysis |
| Albumin | 35-55g/L | Decreases may reflect cirrhosis or malnutrition |
3. Imaging and other examinations
Some patients require further testing to evaluate liver morphology and complications:
| Check type | Applicable situations |
|---|---|
| Liver B-ultrasound | Screening for cirrhosis, fatty liver or space-occupying lesions |
| FibroScan | Non-invasive assessment of liver fibrosis |
| liver biopsy | Determine the staging of liver tissue inflammation and fibrosis (gold standard) |
4. Recommendations for inspection frequency
According to the 2022 "Guidelines for the Prevention and Treatment of Chronic Hepatitis B", the frequency of examinations for different groups of people is as follows:
| Crowd classification | Recommended frequency of inspections |
|---|---|
| Hepatitis B carriers | Review liver function, HBV-DNA and B-ultrasound every 6-12 months |
| Antiviral treatment patients | Monitor viral load and liver function every 3-6 months |
| Cirrhosis patients | Comprehensive examination every 3 months, including alpha-fetoprotein (AFP) screening for liver cancer |
5. Recent hot discussions
Popular topics about hepatitis B testing on social platforms in the past 10 days include:
1."Interpretation of five hepatitis B results": Netizens shared how to distinguish infection status through five indicators.
2."The Necessity of HBV-DNA Testing": Some patients question the value of high-cost testing, and experts emphasize its irreplaceability.
3."Popularization of non-invasive liver fibrosis testing": FibroScan technology becomes a new alternative to liver biopsy.
Summary: Hepatitis B examination needs to be combined with comprehensive serology, biochemistry and imaging evaluation, and regular follow-up is crucial for disease management. If abnormalities are found, seek medical treatment promptly to develop a personalized plan.
