Studies show that nearly 90% of liver cancer patients have been infected with hepatitis B and\/or C (*).\n? To prevent hepatitis B, vaccination is the most effective measure.\n\nBefore receiving the hepatitis B vaccine, it is important to determine whether your body has already been infected with the hepatitis B virus or has developed protective antibodies. The following tests help accurately identify hepatitis B antigens and antibodies:\n\n? HBsAg: Hepatitis B surface antigen. This is the most basic and essential screening test to determine whether a person is currently infected with hepatitis B.\n\n? HBsAb: Hepatitis B surface antibody. This test evaluates the level of protective antibodies against the hepatitis B virus in the body. After completing hepatitis B vaccination, individuals should test HBsAb every 5 years. If the result is below 10 mIU\/mL, a booster dose of the vaccine is recommended.\n\n? Anti-HBc Total: Total hepatitis B core antibody. This test indicates past or present exposure to the hepatitis B virus. Anti-HBc appears early and remains positive for life, even after recovery when HBsAg becomes negative. If a person is HBsAg negative but Anti-HBc Total positive, hepatitis B vaccination is not indicated.\n\n? Regular health screening helps you better understand your health status and take proactive steps to protect yourself and your family through vaccination.\n\n? No fasting required for testing\n? At-home sample collection available upon request\n? Online results with comprehensive doctor consultation\n","protected":false},"excerpt":{"rendered":"<p>Hepatitis B is a dangerous infectious disease caused by a virus that can lead to severe liver damage, including cirrhosis and liver cancer.
