Hepatitis A
Diagnosis of Hepatitis A
Blood tests Doctors suspect hepatitis A in people who have been exposed to the hepatitis A virus and who have typical symptoms, such as jaundice. Testing usually begins with blood tests to determine how well the liver is functioning and whether it is damaged ( Liver Blood Tests ). Liver tests involve measuring the levels of liver enzymes and other substances produced by the liver. If tests detect liver abnormalities, other blood tests are usually done to check for hepatitis virus infection. These blood tests can identify parts of specific viruses (antigens), specific antibodies produced by the body to fight the virus, and sometimes genetic material (RNA or DNA) of viruses.
