HCG values are also doubled after tens of thousands, as long as it is determined to be intrauterine pregnancy, it is normal and no need to worry.
Under normal circumstances, when the fertilized egg is deposited in the uterine cavity, it will begin to secrete HCG, and as the number of days of pregnancy grows, the HCG value will gradually increase. After the 10th week of pregnancy, the placenta starts to secrete progesterone, and the HCG value will increase at a slower rate and will not double.
The reference value of HCG varies in different weeks of pregnancy. At 2-3 weeks of pregnancy, it is about 100-5000u/L, at 3-4 weeks, it is 500-10000u/L, and when it enters 5-6 weeks of pregnancy, the reference value of HCG is 10,000-100,000u/L, which is more than ten thousand.
However, the peak of HCG value is usually in the 10th week, and before that, it will always be doubled. Therefore, it is normal for HCG values to double.
Pregnant women do not need to be anxious, sure that the intrauterine live birth is not a problem, to the 10th week of pregnancy after the HCG value will naturally decline.
