The determination of serum human chorionic gonadotropin is what?

  Many women who are already pregnant know that if they are pregnant with a pregnancy test, the presence of two bars is pregnancy, but many people do not know why there are two bars, and the principle of urine detection of pregnancy. In fact, the main indicator is increased serum human chorionic gonadotropin, or HCG, produced by the placenta, which starts around 10 days after conception.

  The term serum human chorionic gonadotropin may be unfamiliar because it is a specific dynamic indicator for women during pregnancy. The level of human chorionic gonadotropin (HCG) is the basis for accurately determining whether or not to become pregnant in the early stages. It will gradually decrease after 8 weeks of pregnancy, so the serum HCG test is very important.

  The determination of serum human chorionic gonadotropin is what?

  Is the relationship between human chorionic gonadotropin and pregnancy: women of reproductive age in the fertilized egg moves to uterine cavity after implantation, which is pregnant, the formation of embryo, in the process of growth for developing fetus and placenta form-fitting trophoblastic cells will produce a large number of human chorionic gonadotropin (HCG), which can be pregnant women blood circulation and excretion in the urine. Serum and urinary HCG levels rise rapidly from 1 week to 8 weeks of gestation, peak at 8 weeks of gestation, and then slowly decline to moderate levels until the end of gestation. Therefore, changes in the HCG index can be determined by serum test and urine test, so that pregnancy can be accurately determined.

  But there are many exceptions to this test. The usual rise in HCG may not be a sign of pregnancy, but may also be a sign of illness. Incomplete abortion can lead to increased HCG concentrations. Firstly, the misoperation of the early pregnancy test may lead to the failure of the test. Secondly, the HCG concentration in the blood of patients with hydatidiform mole and choriocarcinoma also increases significantly. Men with spermatogonial testicular cancer also have moderately elevated levels of HCG in their blood. The detection of HCG in some patients with threatened abortion can not only understand the secretion function of placental trophoblast cells in advance, but also provide a basis for clinical treatment. Levels of HCG in the blood can be reduced in cases of spontaneous abortion, fetal malformation, and fetal growth restriction.

  So the serum human chorionic gonadotropin test can be used to determine whether a woman is pregnant or not and some major diseases. People who are accurately pregnant need to know more about the HCG test, avoid nervousness during the hospital examination, and the girlfriend who USES the pregnancy test in advance should also be properly handled to ensure the test results are accurate. If abnormal should go to normal hospital in time to check.
