What does anti-HBc positive mean?

anti-HBc or HBcAb (Hepatitis B core antibody) – A “positive” or “reactive” anti-HBc (or HBcAb) test result indicates a past or current hepatitis B infection. The core antibody does not provide any protection against the hepatitis B virus (unlike the surface antibody described above).

Can HBsAg and HBsAb be positive?

Both in vitro simulation and in vivo animal models demonstrated that HBsAg antigen and HBsAb of the same serotypes could not coexist, but HBsAg antigen and HBsAb of different serotype could coexist. HBsAg/HBsAb double positive hepatitis B virus infection could be due to infection of viruses of different serotypes.

What if Mother is HBsAg positive?

Mothers who are positive for both HBsAg and HBeAg have the highest likelihood of transmitting HBV to their newborns. However, infants of mothers who are HBsAg-positive but HBeAg- negative may become infected and develop severe, even fatal, fulminant hepatitis B during infancy (17,18).

What is HBsAg positive symptoms?

What is HBc medical?

What is anti-HBc negative?

A negative total anti-HBc result may indicate the absence of a recent or previous HBV infection (negative HBsAg and anti-HBs). However, a developing infection cannot be ruled out.
