How Hepatitis A Is Diagnosed

Photo Credit: Circle of Docs

A simple blood test from a doctor can determine if a patient is infected with hepatitis A as the virus is present in the blood and feces for up to two weeks before clinical illness or symptoms develop. Doctors diagnose the disease by looking for the presence of hepatitis A antibodies in the blood, which are absent in healthy individuals. This type of antibody is detectable one to two weeks after infection and remains present in the bloodstream for up to fourteen weeks. During the acute stage of the disease, there is also a much higher level of a liver enzyme, which is produced because of liver damage, in the bloodstream. Tests for immunity to hepatitis A involve measuring antibody and enzyme levels in the blood.
