Hepatitis B triple positive transaminase is below 40U/L before labor can be induced. Transaminase is a catalytic enzyme that can promote the conversion of proteins and amino acids, which is widely found in liver cells and other organ cells. The normal value of transaminase should be 10~40U/L, if the index of transaminase is high, it will make the liver function suffer certain damage, and after the damage of the liver function, it will easily cause coagulation dysfunction. Therefore, pregnant women with hepatitis B triple positive need to wait until the aminotransferase is reduced to 40U/L before induction of labor, otherwise it will easily cause postoperative hemorrhage, which is very dangerous for both the fetus and the pregnant woman. If the transaminase is elevated after pregnancy, you need to choose abortion at the early stage of pregnancy, and the higher the month, the higher the risk factor.
