The definition of hepatitis B carrier is very broad. Many people think that the liver function is normal, and people without symptoms can be defined as hepatitis B carriers. Is that really the case? Do two halves of hepatitis B belong to hepatitis B carriers? What do the two halves of hepatitis B represent? The positive results of HBV-245 are mainly HBsAg, E antibody and core antibody, that is, HBV-245 antibody is positive, which means that many people have been infected with HBV before, because most of them are asymptomatic. For semi -245 positive hepatitis B patients, due to their strong immunity, hepatitis B virus has been eliminated, or will be eliminated soon. At this time, most of them are non-infectious and a few are infectious. At this time, HBV can be tested for DNA. If it is positive, it means it is contagious, and if it is negative, it means it is not contagious. Whether it is contagious or not, don't be too alarmed. Most of the infected people can recover after a period of time and develop into hepatitis B 25 positive and hepatitis B 245 positive, indicating that they are infected with hepatitis B virus and have recovered and produced protective antibodies. Do two halves of hepatitis B belong to hepatitis B carriers? Two and a half of 245 hepatitis B positive couples can't be said to be hepatitis B carriers. If the fourth positive term lasts for more than half a year, it has not turned positive. At this time, it is necessary to prevent virus mutation in B. This situation is more dangerous, because once the hepatitis B virus mutates, it will bring great harm to patients.
