In recent years, with the improvement of living standards, people pay more and more attention to health, and hepatitis B five as a preliminary screening and diagnostic means, is one of the people’s physical examination of the mandatory items, then, hepatitis B five each represents what is the significance of it? How to read the lab report? Below, we do a brief analysis of hepatitis B five. Hepatitis B five is also known as the two halves, generally it is divided into the first is the hepatitis B virus surface antigen (HbsAg), the second is the hepatitis B virus surface antibody (HBsAb), the third is the hepatitis B virus e antigen (HBeAg), the fourth is the hepatitis B virus e antibody (HBeAb), and the fifth is the hepatitis B virus core antibody (HBcAb) and the hepatitis B virus core IgM antibody (HBsAb-IgM), which are the most important antibodies of the hepatitis B virus, the most important antibodies of the hepatitis B virus. The fifth is HBcAb and HBsAb-IgM, which play a very important role in the diagnosis of hepatitis B and are commonly used in clinical diagnosis. 1. Hepatitis B Virus Surface Antigen (HBsAg) HBsAg is the sign of hepatitis B infection, and it is also the first viral marker appearing in the serum of the body.HbsAg is the outer shell of hepatitis B virus, which doesn’t contain DNA, so it doesn’t reflect whether the virus is replicated or not, the replication degree, infectiousness, and virus carriers can be positive for HbsAg. 2. Hepatitis B virus surface antibody (HBsAb) is a kind of protective antibody, which can prevent hepatitis B virus from crossing the cell membrane and entering into the new liver cells. positive HBsAb suggests that the body has a certain degree of immunity against hepatitis B virus. 3. Hepatitis B virus e antigen (HBeAg) indicates that hepatitis B is in active stage, which is a sign of viral replication and highly infectious. If HBeAg remains positive for more than 10 weeks, it indicates that the disease may tend to be chronic. 4. Hepatitis B virus e antibody (HBeAb) is the sign of cessation of viral replication. Virus replication is reduced, the infectiousness is weaker, but not completely free of infectiousness. 5. Hepatitis B virus core antibody (HBcAb) is the sign of those who have been infected or are being infected. HBeAb is the total antibody, including HBeAb IgM and HBeAb IgG, the total antibody of HBeAb mainly reacts to HBeAb IgG, the core antibody IgM is the sign of newly infected or viral replication, and the core antibody IgG will be produced after infection, which has certain significance in assisting two-to-half examination. auxiliary two-to-four tests have some significance. In general, if HBeAb IgM is positive and HBeAb IgG is negative suggests acute hepatitis B. If both HBeAb IgM and HBeAb IgG are positive, it is an acute attack of chronic hepatitis B. Detection and analysis of common markers: 1. ② is positive and all others are negative, indicating that the body has resistance to hepatitis B virus and is a healthy person. However, hepatitis B five items should be checked regularly. 2, ①, ③, ⑤ are positive, that is, usually referred to as triple sun, indicating acute or chronic acute attack of hepatitis B, and the virus replication is active and highly contagious. At this time, patients should go to the hospital as early as possible to check HBV-DNA, blood routine, liver function, liver fiber four, coagulation four, ultrasound, alpha-fetoprotein and so on. In life, close contact with immunocompromised people such as children and the elderly should be avoided, but daily activities are generally not contagious. 3. ①, ④, ⑤ are positive, that is, the small triple positive, which means acute or chronic acute attack of hepatitis B, but the virus replication is reduced, and the infectiousness is low, but we should go to the hospital for the relevant examination (the same as the large triple positive). 4. ②, ④, ⑤ are positive, indicating previous hepatitis B virus infection, antibodies have been produced and in recovery stage. At this time, one should go to the hospital for examination, such as ultrasound, liver function, liver fiber four, coagulation four, blood routine, alpha-fetoprotein and so on. 5. ② and ⑤ are positive, indicating previous hepatitis B virus infection, antibodies have been produced and in recovery stage. At this time, one should go to the hospital for examination, such as ultrasound, liver function, liver fiber four, coagulation four, blood routine, alpha-fetoprotein and so on. 6. ④ and ⑤ are positive, indicating that hepatitis B virus has been infected in the past and is now in the stage of recovery, but antibodies have not been produced, so close attention should be paid to the tests of hepatitis B six items, and ultrasound, liver function and so on should also be checked regularly. The above is only a simple analysis of Hepatitis B five items to help you understand the laboratory test, but how to really analyze a laboratory test, should also be based on the clinician with reference to a more comprehensive examination results and the patient’s own medical history for individual analysis, do not blindly.
