Order Hepatitis B Surface Antibody (Immunity) Test from JustLabs for $16 ($34 all-in for a single-test order: $16 + one $18 lab & physician order fee per order). Price includes lab processing at Quest Diagnostics. No insurance required.
A blood test that detects protective antibodies against Hepatitis B, confirming immunity from vaccination or past infection.
The Hepatitis B Surface Antibody (HBsAb or anti-HBs) test measures whether you have protective antibodies against Hepatitis B virus. These antibodies develop either from successful vaccination or from natural immunity after recovering from infection.
Hepatitis B is a serious liver infection that can become chronic, leading to cirrhosis and liver cancer. Vaccination is highly effective at preventing infection, but immunity may wane over time in some people.
This test is commonly used to verify immunity in healthcare workers, confirm vaccination success, and check immunity status in people who may need a booster shot.
