How to double the hcg of IVF after IVF transplantation is not very fast. HCG is human chorionic gonadotropin, and English is the abbreviation of human chorionic gonadotropin. It is a glycoprotein secreted by placental trophoblast cells. And then what? Glycoprotein component of dimer. HCG test paper is the most widely used detection tool for detecting human chorionic gonadotropin.
Blood HCG test is the earliest and most accurate pregnancy test at present. The blood HCG test is usually carried out 8- 10 days after the fertilized egg is implanted, and it is possible to determine whether it is pregnant by drawing blood to check the HCG in the serum. Human chorionic gonadotropin (hcg) is a glycoprotein secreted by placental trophoblast cells and consists of two subunits, a- and b-. After the fertilized egg is implanted, hCG is secreted by trophoblast cells and then enters the maternal blood, and rapidly proliferates (doubling every 1-2 days) until the eighth 8- 10/0 week of pregnancy, reaching a peak, and then slowly decreases the concentration to 18-20 weeks, and then remains stable. Blood HCG is generally detected by serum, including qualitative detection with test paper and quantitative detection with instrument, and the accuracy of quantitative detection with instrument is the highest.
How much hCG value means ectopic pregnancy, and HCG is a specific hormone secreted during pregnancy, then? -HCG can be used to diagnose early unruptured ectopic pregnancy. B-ultrasound in early pregnancy can't judge whether you are pregnant, but now you can use blood HCG to determine. Blood HCG is not only sensitive, but also because? Quantify? Data, you can more accurately judge whether you are pregnant. However, HCG value can not be used as the basis for the diagnosis of ectopic pregnancy, and the diagnosis of ectopic pregnancy should be judged according to the results of further examination.
Before introducing the HCG value of ectopic pregnancy, let's first understand the HCG of normal pregnant women. Normal people? The radioimmunoassay value of -HCG is less than 3. 1. If it exceeds 5, you can consider the possibility of pregnancy. If it exceeds 10, you can basically determine pregnancy. From 35 to 50 days after pregnancy, HCG can rise to more than 2500 IU/L. Urinary HCG in multiple pregnancies is often more than that in singleton pregnancies. The absolute value of serum HCG varies greatly between pregnant women and pregnant women at different stages, and everyone is different. There is no comparability, so we can only compare ourselves.
The amount of HCG secreted by normal villi is very large, and the titer is increasing rapidly every day, increasing by more than 66% every 48 hours. What if? -HCG increases by more than 66% every two days, which can be diagnosed as intrauterine pregnancy; If the increase is less than 66%, it is likely to be ectopic pregnancy or intrauterine pregnancy dysplasia. Once the test result may be ectopic pregnancy, you should go to the hospital for examination to determine whether it is ectopic pregnancy and treat it in time.
