Hepatitis B Test – Understanding the Complexity of Hepatitis B Infection
Hepatitis B is a viral infection that attacks the liver and can lead to chronic disease, cirrhosis, and liver cancer. The Hepatitis B test detects the Hepatitis B virus (HBV) and several serological markers to assess whether the infection is acute or chronic and to guide treatment decisions.
Indications for Hepatitis B Test:
● Routine screening: For high-risk individuals, such as healthcare workers, people with multiple sexual partners, or individuals with a history of intravenous drug use.
● Liver disease symptoms: To confirm hepatitis B infection in individuals experiencing jaundice, fatigue, abdominal pain, or unexplained weight loss.
● Chronic hepatitis B monitoring: For individuals with a history of chronic hepatitis B to assess viral load and liver function.
Methods to Detect Hepatitis B:
● HBsAg (Hepatitis B Surface Antigen): A marker for active infection. A positive result indicates the virus is present in the body.
● Anti-HBs (Hepatitis B Surface Antibody): Indicates immunity due to vaccination or recovery from previous infection.
● Anti-HBc (Hepatitis B Core Antibody): Indicates exposure to the virus; IgM suggests acute infection, while IgG suggests past exposure.
● HBV DNA (PCR or HCV RNA load): Used to measure the viral load, helping to assess the severity and determine whether treatment is needed.
Normal Range:
● HBsAg: Negative (no active infection).
● Anti-HBs: Positive after vaccination or recovery.
● Anti-HBc IgM: Positive during acute infection.
● Anti-HBc IgG: Positive after past infection or exposure.
Abnormal Test Significance:
● HBsAg positive: Indicates active Hepatitis B infection.
● Anti-HBs positive: Indicates immunity due to vaccination or past infection.
● Anti-HBc IgM positive: Suggests acute or new infection.
● Anti-HBc IgG positive: Indicates chronic or resolved infection.
Management:
● For active infection: Antiviral therapy (e.g., tenofovir, entecavir) may be prescribed to reduce the viral load and prevent liver damage.
● For chronic infection: Long-term monitoring and treatment may be required to manage liver health and prevent progression to cirrhosis or liver cancer.
Price in India:
● Rapid Tests: ₹500–₹2,000.
● Advanced Testing: Costs may vary depending on the facility and the type of test.
FAQs
What is the difference between HBsAg and Anti-HBs?
HBsAg indicates active infection, while Anti-HBs indicates immunity either from vaccination or past infection.
How is Hepatitis B transmitted?
Hepatitis B is spread through blood, semen, or other bodily fluids, and can also be transmitted from mother to baby during childbirth.
Disclaimer:
Hepatitis B tests should be interpreted by a healthcare provider, as the results may require additional tests or clinical evaluation to determine whether treatment is necessary.
