FAQ
Frequently asked questions
What is hepatitis B?
Hepatitis B is a viral infection that attacks the liver. It can be transmitted through blood, semen, or other body fluids. While many people recover, some can develop chronic hepatitis B, which can lead to serious liver problems.
How is hepatitis B transmitted?
Hepatitis B is spread when blood, semen, or other body fluids from an infected person enter the body of someone who is not infected. This can happen through sexual contact, sharing needles, or from an infected mother to her baby at birth.
What is the difference between Hepatitis B core antibody and Hepatitis B surface antibody?
The Hepatitis B core antibody (anti-HBc) indicates past or present infection. The IgM version specifically points to a recent infection. The Hepatitis B surface antibody (anti-HBs) typically indicates immunity, either from vaccination or recovery from a past infection.
Can this test detect chronic hepatitis B?
While this test is a strong indicator of acute infection, other hepatitis B markers are usually needed to diagnose chronic hepatitis B. A clinician will interpret these results in the context of your overall health and other test results.
