Hepatitis B Surface Antibody Immunity, Quantitative

Description

The Hepatitis B Surface Antibody Immunity, Quantitative blood test is a laboratory test that measures the quantity or concentration of antibodies against the surface antigen of the Hepatitis B virus (HBV). This test provides a numerical value indicating the level of Hepatitis B surface antibodies (anti-HBs) present in the blood.

 

Hepatitis B Surface Antibodies (Anti-HBs): These antibodies are produced by the immune system in response to either vaccination against Hepatitis B or natural infection with the virus. The presence of anti-HBs is an indicator of immunity to Hepatitis B.

Quantitative Test: Unlike a qualitative test that provides a simple positive or negative result, a quantitative test measures the actual amount or concentration of antibodies present in the blood. In the context of the Hepatitis B Surface Antibody Immunity, Quantitative test, it quantifies the level of anti-HBs.

Immunity Assessment: The quantitative measurement of Hepatitis B surface antibodies helps assess the strength of immunity. Higher antibody levels are generally associated with a stronger and more durable immune response.

This test is often used in the following situations:

Vaccination Response: It can be used to confirm the effectiveness of Hepatitis B vaccination by measuring the level of anti-HBs after completing the vaccine series.

Post-Infection Monitoring: For individuals who have recovered from a Hepatitis B infection, the test can help determine the presence and level of immunity.

Healthcare Workers and High-Risk Individuals: In certain settings, such as healthcare or specific high-risk populations, the quantitative test may be used to ensure that individuals have sufficient antibody levels for protection against Hepatitis B.

Hepatitis B Surface Antibody Immunity, Quantitative - This assay is used to determine immune status for Hepatitis B as ≥10 mIU/mL as per CDC Guidelines.
