Checking time Generally speaking, the hepatitis B two pairs of half can rarely appear considerable changes, every 1-2 years to test a can, or find liver function fluctuations when testing once, if the liver function has been good, there is no need to check the liver function every time. It is recommended to check the liver function and have an ultrasound every three to six months or so. The hepatitis B two pairs of half that hepatitis B five is the most commonly used hepatitis B virus marker, hepatitis B two pairs of half is divided into qualitative and quantitative two, we often see are qualitative examination, hepatitis B two pairs of half qualitative examination can only provide qualitative results, that is, negative or positive. The quantitative hepatitis B two-to-one test remedies this deficiency by providing accurate values for various indicators, which are important for the treatment and healing of hepatitis B disease. It is important for patients to have a quantitative hepatitis B two-and-a-half test, which has many advantages. It is based on the original test of “hepatitis B two-and-a-half” and “liver function”, but it is also a scientific and in-depth test to find the best treatment plan for hepatitis B, which includes It includes the amount of hepatitis B virus present in the blood, whether it is replicating, whether it is contagious, whether it is necessary to take medication, which type of antiviral drug is suitable and whether it is resistant to medication, etc. It provides a scientific and formal and complete treatment plan for hepatitis B. Analysis of the results The five indicators can be shown in the following forms when they appear on the laboratory test, and their significance varies, so they must be carefully identified. In the past, it was believed that the small triplet of hepatitis B indicated that the infectiousness of the patient had been significantly or relatively reduced, and the degree of virus replication had been reduced or significantly alleviated. However, in recent years, it has been found that many patients with hepatitis B minor triple-positive have abnormal liver function and are also positive for hepatitis B virus deoxyribonucleic acid (HBV-DNA), and their condition is persistent. This is due to the mutation of hepatitis B virus. This is a result of the mutation of the hepatitis B virus. It should not be ignored clinically and treatment is still needed for this condition. The criteria for identifying whether hepatitis B minor tri-positive is good or bad are: if liver function is always normal and hepatitis B virus deoxyribonucleic acid is negative, it is a good phenomenon; if hepatitis B virus deoxyribonucleic acid is positive and liver function is abnormal, it is a bad phenomenon. Second, hepatitis B small two-positive, that is, hepatitis B surface antigen, core antibody positive at the same time, the clinical significance of this form and hepatitis B small three-positive basic consistent, small three-positive and small two-positive sometimes can change each other. Third, hepatitis B major tri-positive, that is, hepatitis B surface antigen, e antigen and core antibody positive at the same time. This is the classic and normative pattern of the complete existence of the hepatitis B virus. A positive e antigen indicates that the hepatitis B virus is actively replicating in the body and is highly infectious. At this time, check the liver function, if the transaminases are elevated, or do a liver puncture test to confirm the presence of inflammation, indicating that the hepatitis is in a state of morbidity, must be treated, can use antiviral and restore liver function treatment. Fourth, simple surface antibody positive, surface antibody is immune and protective antibody to hepatitis B virus, is neutralizing antibody, the purpose of playing hepatitis B vaccine is to let it produce, some people even without vaccination, will be infected with the virus, the initiative to produce surface antibody, which is certainly a good thing. The higher the titer of hepatitis B surface antibody in the serum, the stronger the protection and the longer it lasts (more than 3 to 5 years). After re-infection with the hepatitis B virus, the titer of hepatitis B surface antibody can rise significantly within 2 weeks. However, there are cases of hepatitis B surface antibody positivity with hepatitis B, which may be a different subtype of infection. 90% or more of those who receive hepatitis B vaccination will have positive hepatitis B surface antibody. In rare cases, both surface antigen and antibody are positive, commonly in different subtypes of hepatitis B virus infection; in immunocompromised patients, the hepatitis B surface antibody in the blood often cannot handle the surface antigen; or they are infected with hepatitis B virus with mutations in the s gene. The hepatitis B virus is a major cause of hepatitis B infection. infectious. Core antibody IgG can persist for years to decades and is a sign of previous infection by the hepatitis B virus, indicating that there is no longer any problem. These cases indicate that the hepatitis B virus has been infected in the past, but the virus is now cleared and the body is healthy again. However, some patients may also have abnormal liver function and positive HBV-DNA in this case, so it is still important to consider whether there is any virus mutation. The significance of the Hepatitis B 5 test is to check whether you are infected with Hepatitis B and the specific circumstances of the infection, and to distinguish between major and minor triplets. The day before the hepatitis B test, it is best not to take any medications, especially those that are harmful to the liver, such as antipyretic and analgesic drugs, hormones, etc. It is also recommended not to drink alcohol before the hepatitis B test, but if you are simply checking hepatitis B and half, you can do so without fasting.
