    Hepatitis A Virus Test



    Why It Is Done

    Hepatitis virus testing is done to:

    • Identify the type of hepatitis virus causing a hepatitis infection.
    • Screen people (such as doctors, dentists, and nurses) who have an increased chance of getting or spreading hepatitis A.
    • Screen potential blood donors and donor organs to prevent the spread of hepatitis A.
    • Find out whether a person has antibodies after getting a hepatitis A vaccine. If you had this vaccine and you now have antibodies to the hepatitis A virus (anti-HAV antibodies) in your blood, this means the vaccination was effective (you are immune to hepatitis A).
    • Find out if a hepatitis A infection is the cause of abnormal liver function tests.
