Hepatitis Virus Studies
- Hepatitis-B Surface Antigen
Antibodies are produced by the body in response to a viral or bacterial infection. HAV (Hepatitis A Virus) is very contagious and is spread by contamination from the stool of an infected person; from their unwashed hands into food and drink. Symptoms are usually mild, and do not require medical attention or treatment. HAV-Ab/IgG and HAV-Ab/IgM are the two antibodies that are used to diagnose HAV.
Hepatitis B virus (HBV) takes a long time to develop, is spread by blood or other body fluids, progresses rapidly, and usually leads to death. It is possible to be a carrier of HBV, with no physical symptoms, but you can still spread the disease to others. Hepatitis B Surface Antigen (HBsAg) is the blood test that is mainly used to diagnose HBV. Other tests used to diagnose HVB are Hepatitis B Surface Antibody (HBsAb), or Hepatitis B Core Antibody (HBcAb).
Hepatitis C (HCV) is spread through blood or other body fluids, progresses very slowly, has a more chronic nature than HBV, and will eventually lead to cirrhosis. HCV infection has also been linked to the development of liver cancer.
