The 14th day after the embryo is transferred into the uterus is equivalent to the 28th day of pregnancy. At this time, the aspect ratio of hcg is between 50-500miu/ml. Because each hospital outpatient department has different testing equipment, the production test results may be slightly different. The test results of the local hospital outpatient department should be used as the standard. Then within 6 weeks of pregnancy, if hcg does not exceed 10,000, hcg will generally increase by doubling every two days, and can be adjusted according to the doubling of hcg. To further understand the early growth and development of test tube embryos. Because the value of hcg level increase during pregnancy varies greatly among different individuals, the range of standard values is also very large, and there is no fixed standard. On the 14th day after successful fetal sac transfer, that is, shortly after the sperm and egg combine and the embryo implants, which is equivalent to the 4th week of pregnancy, the hCG level may fluctuate between 500-10000. The hCG level in twin pregnancy increases significantly than that in single pregnancy, but there is no fixed standard. To evaluate whether the hCG level is normal during pregnancy, you need to follow up several times and compare the test results. If the hCG level increases at a rate of doubling every other day, it is normal. If the doubling is not good, it is considered that the embryonic development is not good. The standard HCG blood level of twin babies after test tube transplantation can be tested for hCG gonadotropin level about 14 days after test tube transplantation. If they are twins, there will be individual differences at 200IU/L. When a woman undergoes in vitro fertilization, two test tube embryos will be transplanted to increase the chance of pregnancy. If the HCG value in the blood rises significantly, it cannot be confirmed as a twin pregnancy. A gynecological B-ultrasound will be performed about 10 days after the menstrual period is delayed. If two gestational sacs are found in the uterine cavity and there are two fetal heartbeats, it will generally be confirmed as a twin pregnancy. However, when a woman has twin pregnancy, it will also increase the occurrence of pregnancy complications, such as twin intrauterine syndrome, anemia during pregnancy, hypertension during pregnancy, etc. Regular follow-up visits are required to reduce and prevent the occurrence of complications as much as possible to ensure the safety of mother and child. |
