Patients who come to the center for pregnancy assistance technology will do some preoperative tests, including the hepatitis B test, many people get the results and see that some have a plus sign, but they do not know what it means, so today we will tell you how to read the hepatitis B test results. A, hepatitis B two to half Hepatitis B test is usually 5, including 2 pairs of antigen antibody and a separate 1 antibody, so also known as hepatitis B two to half check, where the antigen from the hepatitis B virus (HBV), and the body against the antigen to produce specific antibodies. 1, BsAg: Hepatitis B surface antigen, is a sign of hepatitis B virus (HBV) infection, the early appearance of the amount of infection related to (6 days to 6 months). HBsAg is a component of the HBV membrane protein, which itself is not infectious. 2, HBsAb: Hepatitis B surface antibody, is a sign of protective immunity, mostly seen in the recovery period of hepatitis B, because the immune system against HBsAg production, mostly seen in patients who have been vaccinated against hepatitis B or once infected but have recovered. 3, HBeAg: Hepatitis B e antigen, a marker of HBV replication and infectiousness, related to the severity of liver damage. Acute hepatitis B HBeAg appears later than HBsAg and disappears before HBsAg, and persistent positivity for ≥10 weeks indicates chronicity. 4, HBeAb: Hepatitis B e antibody, it is generally believed that the appearance of HBeAb indicates a significant reduction in its infectiousness, the disease tends to stabilize and recovery. hBeAb generally does not exist at the same time with HBeAg, usually after the e antigen turns negative, indicating that the hepatitis B virus replication is reduced. 5, HBcAb: Hepatitis B core antibody, in the acute stage for the sign of HBV infection, indicating that the virus replication and infectious. Core antibody positivity lasts for a long time and needs to be analyzed in conjunction with other items, most of the positivity alone is due to previous infection. (Note: HBcAg is the hepatitis B core antigen, representing the active replication of the hepatitis B virus, but because there is very little free HBcAg in the serum, it is difficult to detect HBcAg directly in the serum using conventional methods, so this is not a routine test.) The antibodies produced by the body can be divided into various types and are clinically tested for Ig M and Ig G. Ig M mostly indicates recent infection, while Ig G is antibody to previous infection. The term “major triple positive” refers to positive surface antigen, e antigen and core antibodies. It is generally believed that “major triple-positive” is relatively more contagious and more dangerous. “Minor triple-positive” refers to positive surface antigen, e antibody and core antibody indicators. It is usually transformed from “major triple-positive” and is generally considered to be less contagious than “major triple-positive”. The vertical transmission of hepatitis B virus can be transmitted to the next generation through vertical transmission, which can be divided into 1, preuterine infection: through infected sperm or eggs; 2, intrauterine infection: placental villi breakage during pregnancy or swallowing amniotic fluid can lead to infection; 3, infection during labor: contact with maternal blood or vaginal secretions during delivery can cause infection; 4, postpartum infection: close contact between mother and child after delivery (saliva, sweat, breast milk, etc.) 4. Postpartum infection: the close contact between mother and child (saliva, sweat, breast milk, etc.) after delivery can cause infection. The higher the level of hepatitis B virus replication activity in the mother, the greater the risk of vertical transmission. The hepatitis B virus is mainly transmitted by the sperm of the male partner: HBV DNA is present in the sperm of hepatitis B patients in the form of free and integrated forms. Free HBV DNA is attached to the sperm cell membrane and is infectious; integrated HBV DNA is integrated into the sperm chromosome by penetrating the sperm cell membrane. Studies have shown that ART is effective in reducing the risk of transmission of the virus from male hepatitis patients to their spouses and offspring. The Center’s Data Review Office bases its decision on the fact that patients with “major triplets” should first be seen by the Department of Hepatology; patients with “minor triplets” can enter the week if there are no significant abnormalities in liver or kidney function indicators. The main consideration is the risk of vertical transmission, so how to assess the risk of vertical transmission? The risk of vertical transmission is not related to the type of hepatitis, but mainly to the amount of HBV DNA in the blood, and the risk of vertical transmission increases when the amount of HBV DNA in the blood is ≥10^6. Since hepatitis B virus replication is present in both “major triplets” and “minor triplets”, it is recommended that “major triplets”, “minor triplets” and other patients who feel unwell should be treated. We recommend that patients with “major triple-positive”, “minor triple-positive” and other patients who feel unwell go to the hepatology department first. For those who are hepatitis B carriers or those who have relapsed and worsened during pregnancy, the risk of infection in the offspring can be reduced by drug blockade during the second trimester.
