Hepatitis B titer blood test

A Hepatitis B titer blood test is a test that measures the level of hepatitis B antibodies in a person's blood. These antibodies are produced by the immune system in response to infection with the hepatitis B virus. The test is used to determine whether a person has been infected with hepatitis B in the past, and if so, whether their body has been able to fight off the infection or if the virus is still present and active. The test results are reported as a numerical value, called the titer, which reflects the concentration of hepatitis B antibodies in the blood. A high titer indicates a strong immune response to the virus, while a low titer may indicate a past infection that has since been cleared by the body or a chronic, ongoing infection. The test is often used in conjunction with other tests to diagnose and monitor hepatitis B infection.
