Whether HCG value around 90IU/L is normal or not needs to be judged in the context of the actual situation. In most cases, only after pregnancy will lead to a rising HCG value, but at different stages, the size and changes of HCG value are different. If the pregnancy is new, the HCG value of about 90IU/L is usually normal, because at this time the fertilized egg may have just completed the implantation, and is gradually developing into an embryo, the HCG value of the pregnant woman’s body will gradually rise. However, if the HCG value is around 90IU/L after 5-6 weeks of pregnancy, it is an abnormal situation because the low HCG value has the risk of miscarriage, embryonic arrest and ectopic pregnancy, and you should go to the hospital for an ultrasound examination to determine the pregnancy situation, and then to clarify the reasons for the decrease in the HCG value. If there is an abnormal rise in the HCG value when the body is not pregnant, and if it continues to rise after reaching 90 IU/L, then attention should be paid to whether it is caused by choriocarcinoma. In the process of pregnancy, doctors will closely observe the HCG value of pregnant women to determine whether the pregnancy is normal or not, of course, if there is an abnormal decrease, it is necessary to clarify the cause.
