Hepatitis B Surface Antibodies (HBsAb) Quantitative
This test measures the quantity of antibodies against the hepatitis B surface antigen (anti-HBs) in the blood. It is used to assess immunity after vacciNot Applicabletion or previous infection. High levels suggest protection against future hepatitis B infection.
The Hepatitis B Surface Antibody (HBsAb) test measures the level of antibodies produced in response to the Hepatitis B surface antigen (HBsAg). This test can be quantitative, meaning it measures the actual amount of antibody present in the blood.
- HBsAb is typically present after recovery from Hepatitis B infection or after vaccination against the virus.
Why consider this test?
- Detecting immunity: The test is used to determine whether an individual has immunity to Hepatitis B, either from a previous infection or from vaccination.
- Monitoring vaccination response: It helps assess the effectiveness of the Hepatitis B vaccine.
- Assessing recovery from infection: After an individual recovers from Hepatitis B, the presence of HBsAb indicates immunity and recovery.
Who should get this test done?
- Individuals who have received the Hepatitis B vaccine to check if they have developed sufficient immunity.
- People recovering from Hepatitis B infection to assess if they have cleared the virus.
- People with Hepatitis B exposure or at risk of infection who need to confirm their immunity status.
More Information
A positive result for HBsAb means the person is immune to Hepatitis B, either due to previous infection or vaccination. Negative results may indicate no prior exposure or immunity.
