Overview
The screening for hepatitis A is based on blood tests that search for antibodies for the hepatitis A virus. The test looks for the IgG anti-HAV, which remains elevated after acute disease.[1]
Screening
A positive antibody result may indicate: [1]
- Previous HAV infection
- Hepatitis A vaccination
A positive test shows that the person is immune to the disease. [1]
- A negative test shows that the person:[1]
- Has never been infected with the HAV
- Has never been vaccinated against HAV
- Is vulnerable to the HAV infection
