Blood positivity means that certain items can be detected from the blood circulation and should be analyzed for the specific items. A positive result is the opposite of a negative result. In clinical practice, for qualitative tests it would mean that a negative result is the meaning of not being able to be detected, while a positive result is the meaning of being able to be detected, and what the specific item is would represent what the meaning is. If the corresponding positive result is a hepatitis B surface antibody, which is a protective antibody, a positive result means that it can be detected from the blood circulation, indicating that immunity to the hepatitis B virus has been acquired. But if it is other antibodies, such as HIV antibodies, because the infection does not heal, and it is not a protective antibody, so a positive HIV antibody only means that you are currently an HIV-infected person, so the different items and meanings are very different. If the corresponding positive antibody refers to antibodies to the hepatitis C virus, it means that it is likely that you are infected with the hepatitis C virus. Because some people can already be cured after being infected with the hepatitis C virus, it is also necessary to check the RNA quantification of the hepatitis C virus to be able to determine if you are currently a hepatitis C patient.
