Hepatitis B is a liver infection caused by the hepatitis B virus (HBV). It can range from a mild illness lasting a few weeks to a serious, lifelong condition affecting the liver. The Hepatitis B Panel - Immunity Screen is an important diagnostic tool in determining an individual's immunity status to Hepatitis B. This test checks for different proteins in the blood that are produced in response to the hepatitis B virus. The test can help determine whether you have a current or past infection or if you are immune to Hepatitis B because of vaccination or recovery from past infection.
HBcAb (Hepatitis B core antibody) is an antibody produced in response to a protein in the core of the hepatitis B virus. It can indicate either a current or past infection. Anti HBs (Hepatitis B surface antibody) is an antibody that provides immunity against the hepatitis B virus. It appears in the blood following a successful vaccination or recovery from infection. HBsAg (Hepatitis B surface antigen) is a protein found on the surface of the virus and is the earliest indicator of an acute infection.

This test is important for understanding your immunity status regarding Hepatitis B. Knowing whether you are immune, at risk, or currently infected with Hepatitis B helps in taking necessary precautions or treatments to prevent the spread of the virus and protect your liver.
No, fasting is not required for the Hepatitis B Panel - Immunity Screen. You can eat and drink normally before the test.
A positive HBcAb result means that you have been infected with Hepatitis B at some point. It does not distinguish between a current or past infection.
A positive Anti-HBs result indicates that you are immune to Hepatitis B, either because of vaccination or because you have recovered from an infection.
A positive HBsAg result indicates that you are currently infected with Hepatitis B.
You should get this test done if you are at risk for Hepatitis B infection, if you are healthcare personnel or working in a healthcare facility, if you are about to receive the Hepatitis B vaccine, or if your doctor recommends it based on your health history.
This test provides information on whether you are currently infected with Hepatitis B, have been infected in the past, or are immune to the infection.
The frequency of testing depends on your risk factors and health status. Your doctor will provide guidance on how often you should be tested.
A negative HBsAg result, positive Anti-HBs, and negative HBcAb would indicate immunity due to vaccination. A negative HBsAg, positive Anti-HBs, and positive HBcAb indicate immunity due to past infection. A positive HBsAg indicates a current infection.
If you are not immune to Hepatitis B, it is advisable to get vaccinated. Also, practice safe sex, avoid sharing needles, and exercise caution if you are in a high-risk environment for Hepatitis B exposure.
Factors that can affect the levels of these markers include the stage of infection, vaccination status, immune system health, and exposure to the virus.
If the test results are abnormal, indicating a current infection or lack of immunity, consulting a doctor specializing in liver diseases or an infectious disease specialist is advisable.
The test is highly indicative of your immunity or infection status but additional tests may be needed to understand the complete picture, especially in cases of recent exposure or chronic infection.
Yes, if the test indicates that you lack immunity to Hepatitis B, it is highly recommended to get vaccinated to protect yourself against the virus.
Understanding your immunity status to Hepatitis B is crucial, especially if you are at risk of exposure. The Hepatitis B Panel - Immunity Screen helps to identify whether you are immune to the virus, have had a past infection, or are currently infected. This information is vital in ensuring timely interventions and taking steps to protect your health. If you are not immune, getting vaccinated is an effective way to reduce the risk of infection. Regular screening and consultation with a doctor are essential for monitoring and managing your Hepatitis B status.
