HBc IgG

Hepatitis B Virus (HBV) is one of the most common causes of liver inflammation. Your immune system makes IgM antibodies against HBV during the active stage several weeks after you are first infected. The IgG variant is produced later, and you will likely have a positive HBcAb IgG test for the rest of your life. People with the hepatitis B vaccine will not have these antibodies in their blood.
