This is your "immunity passport" to Hepatitis B. The Anti-HBs test is the single, definitive test that confirms you are protected. It detects the 'surface' antibodies, which are your body's "shield." A positive result is the goal: it means you are immune, either from a successful vaccination or from a full recovery from a past infection. Our "titre" test also quantifies your level of protection. This is the essential test for all healthcare workers, travelers, and anyone checking their vaccination status. Get the definitive proof of your immunity.
