The two indexes of progesterone and HCG during pregnancy are important indicators to measure embryos and fetal health.But, do you know the expectant mother?Without any symptoms or no miscarriage or fetal stopping before, HCG and progesterone are low, and they are not necessarily abortion, but the chances will be higher.What is the normally HCG and progesterone value?What is the relationship between them and abortion?Today I will be popular for everyone:
On the 6th day after the fertilization, the fertilized egg nourishment layer formed and secreted a trace HCG. When the fertilized egg was imposed on the bed for 7 to 8 days, HCG could be detected in the blood.EssenceThe amount of the amount of nourishing cells is directly proportional. Early pregnancy secretion increases rapidly. By 8 to 10 weeks of pregnancy, the peak is up to 10%of the peak from 1 to 2 weeks.Therefore, it is difficult to use a single HCG result to judge threatened abortion or ectopic pregnancy.
During normal pregnancy, the serum HCG value is directly related to the number of pregnancy weeks. Different gestational weeks, the HCG (IU/L) value is of course different, and the trend of positive increasing changes.For example, 0.2-1 weeks of pregnancy, HCG value is 5-50; 1-2 weeks of pregnancy, HCG refers to 50-500; 2-3 weeks of pregnancy, HCG value is 100-5000; 3-4 weeks of pregnancy, HCG value is 500 is 500-10000; HCG value at 4-5 weeks of pregnancy is 1000-50000; 5-6 weeks of pregnancy, HCG value is 10000-100,000; 6-8 weeks of pregnancy, HCG value is 15000-200,000-100000.
According to breeding experts, progesterone was secreted by nourishing cells and luteum before 8 to 10 weeks of pregnancy, and mainly from the placenta after 8-10 weeks.The amount of progesterone gradually increased during the entire pregnancy, and the rise in the early stages of pregnancy was slow, and the mid -term accelerated, reaching a peak at a full month of pregnancy.Serum progesterone is quite stable within 5 to 12 weeks of pregnancy, and has little to do with pregnancy.
The change in the amount of progesterone is a reliable indicator to measure whether the luteal function and the development of the placenta.Due to the stable blood level in the early pregnancy, no continuous monitoring is required to provide doctors with a diagnosis basis earlier.
Next, let’s understand how the progesterone value of women after pregnancy changes.Under normal pregnancy, the progesterone value should be 63.4-94.5 during early pregnancy, and 95-150 during pregnancy; at 150-1500 during late pregnancy.
The synergy of HCG and progesterone, on the one hand, allows the embryo to obtain nutrients, on the other hand to ensure the safety of the embryo, so it is indispensable.HCG has doubled. Due to the lack of nutrients in the embryo, it may be slow or even stopped. Instead of progesterone, the embryo will be unstable in bed, causing bleeding or even abortion.
However, due to the slow growth of the blood HCG and it takes a certain time to observe it, it is not possible to detect whether the HCG value cannot be judged whether the fetal abortion is not possible.Performatone has a certain stability, and combined with B -ultrasound examination, it greatly improves the diagnostic rate, and at the same time provides valuable reference significance for predicting early pregnancy ending.Jointly detecting serum HCG and progesterone can judge the prognosis of pregnancy earlier and more accurately, and is significantly better than the individual detection of serum HCG or progesterone.
