Overview
Screening for hepatitis A is performed through the detection of hepatitis A virus antibodies in the blood. IgG anti-HAV remains elevated after acute disease.[1]
Screening
A positive antibody result demonstrates that the person is immune to the disease due to: [1]
- Previous HAV infection, or
- Hepatitis A vaccination
A negative test demonstrates that the person:[1]
- Has never been infected with HAV
- Has never been vaccinated against HAV
- Is vulnerable to the HAV infection
