What does hepatitis C antibody (HCV) mean?

　　Hepatitis C antibody (anti-HCV) refers to the immune antibodies produced by the body in response to the hepatitis C virus (HCV).

　　When a person is infected with hepatitis C, the immune system produces anti-HCV antibodies to fight the virus. Therefore, testing for anti-HCV antibodies can determine whether someone has ever been infected with hepatitis C.

　　However, a positive anti-HCV antibody test does not necessarily mean an active hepatitis C infection. In some individuals, the immune system may clear the virus after infection, but anti-HCV antibodies may still remain. Thus, if the anti-HCV antibody test is positive, further testing using HCV RNA nucleic acid detection is required to confirm whether an active hepatitis C virus infection is present.

　　Note that hepatitis C is a liver infection caused by the hepatitis C virus and can be transmitted through blood. If left untreated, it may lead to serious complications such as cirrhosis and liver cancer. Therefore, timely testing and treatment of hepatitis C are crucial.
