Hepatitis B Core Antibody (HBcAb or Anti-HBc) This antibody does not provide any protection or immunity against the hepatitis B virus. A positive or reactive test indicates that a person may have been infected with the hepatitis B virus at some point in time.
What is hepatitis B core?
The hepatitis B core antibody (HBcAb) is produced by your immune system after infection by the hepatitis B virus, and it can persist for life. It is a sign that you either have an new, active (acute) hepatitis B infection or that you acquired hepatitis B in the past.

Any value between 1 and 5 s/c is indeterminate and should be repeated. For hepatitis B surface antibody (anti-HBs), a level less than 5 mIU is considered negative, while a level more than 12 mIU is considered protective. Any value between 5 and 12 mIU is indeterminate and should be repeated.
Can you test positive for hep B after vaccine?
Published studies have found that transient HBsAg-positivity can be detected for up to 18 days after HepB vaccination (up to 52 days among hemodialysis patients).
Which is worse hepatitis B or C?
Comparing hep B vs. hep C, studies show hepatitis B causes more liver-related deaths than hepatitis C. Also, hep C is curable, while hep B can become chronic and require lifelong management. Although the hep B vaccine is effective, differences in hep B and C viruses have slowed hep C vaccine development.
Is Hep B vaccine good for life?

How did my husband get hepatitis B?

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
