Hepatitis Immunity Detection & Vaccine Testing in Washington DC
Hepatitis Immunity Detection & Vaccine Testing can be ordered without a referral, and this guide covers what to expect. This test checks if your body has protection against the Hepatitis A and B viruses, either from vaccination or past infection.
What this test is
Hepatitis immunity testing looks for antibodies in your blood that indicate your immune system is prepared to fight off Hepatitis A and B infections. It helps determine if a vaccine was effective or if you have natural immunity.
What it measures
- Hepatitis A Antibody (Anti-Hepatitis A IgG) — reflects immunity to Hepatitis A
- Hepatitis B Surface Antibody (Anti-Hepatitis B s) — reflects immunity to Hepatitis B
- Hepatitis B Core Antibody (Anti-Hepatitis B c) — may indicate past Hepatitis B infection
What the test involves
A healthcare professional will collect a small blood sample by performing a standard venipuncture, also known as a blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
