Hepatitis B virus e antigen (HBeAg)

Hepatitis B virus e antigen is a soluble protein present in the core particle in a concealed form, distributed in the intercellular space and may be involved in viral replication. Hepatitis B virus e antigen is the core part of hepatitis B virus, so it is generally considered that hepatitis B virus e antigen positive is a contagious marker. Hepatitis B virus e antigen can be detected during the incubation period and the whole disease course; hepatitis B virus e antibody is the corresponding antibody of hepatitis B virus e antigen, and it is generally considered that hepatitis B virus e antigen disappears and hepatitis B virus e The appearance of antibodies is a sign that the condition tends to improve, but it does not mean that the hepatitis B virus DNA stops replicating or the infectivity disappears. Basic Information Specialist classification: Infectious disease examination and classification: immunological examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: normal. Positive: Hepatitis B virus is replicating and infectious, and it can be an acute acute infection of hepatitis B virus. The higher the hepatitis B virus DNA level, the higher the e antigen positive level. This long-term positive in two pairs of hepatitis B suggests that hepatitis B virus continues to replicate in the body, chronic inflammation of the liver, and poor prognosis. Tips: If the examiner wants to check liver function (hepatitis B ultrasound) at the same time, it must be fasted. Normal value negative. Clinical significance 1. HBeAg is an important indicator of hepatitis B virus replication. The persistent positive HBeAg indicates the presence of active replication of hepatitis B virus, suggesting that it is highly contagious and easily becomes chronic. 2. Generally, HBeAg appears in HBsAg-positive. When HBeAg-positive and HBsAg-negative are encountered, it is considered that the method of detecting HBsAg is not sensitive, or there is rheumatoid factor interference in serum. 3. "Da Sanyang" means that hepatitis B surface antigen (HBsAg), E antigen (HBeAg) and core antibody (HBcAb) are positive in the two-to-half test of hepatitis B. It is suggested that hepatitis B virus infection is active and infectious. It does not indicate whether the condition is serious. Positive results may be diseases: hepatitis B, acute and chronic hepatitis precautions The results of the examination must be combined with several other hepatitis B inspection items. Inspection process 1. Intravenous blood draw, laboratory test. 2. Serological examination of the virus. Not suitable for the crowd People with reduced hematopoietic function such as leukemia, various anemia, myelodysplastic syndrome, or people with thrombocytopenia should pay attention to blood draw, and should not take more or more blood. Adverse reactions and risks 1. After the blood is drawn, do not press the needle hole to avoid subcutaneous hematoma. If there is a small piece of bruise in the blood, it is slightly tender, please don't panic, you can do hot compress after 24 hours to promote the absorption of blood. The general small amount of congestion will gradually absorb in 3 to 5 days and the color will become lighter and return to normal. 2. After the blood draw, symptoms such as dizziness, vertigo, fatigue, etc. should be immediately supine, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved.
