Hepatitis A Immunity Testing

Hepatitis A immunity testing is a blood test that is performed to determine if a person has immunity to the hepatitis A virus. This test measures the presence of antibodies in the blood that indicate whether the person has been previously infected with the virus or has been vaccinated against it. Immunity testing is often recommended for individuals who may be at risk of exposure to the hepatitis A virus, such as healthcare workers, travelers to countries where the virus is endemic, or individuals with liver disease. Knowing a person's immunity status can help guide decisions about vaccination and preventive measures to protect against hepatitis A infection.
