If hcg increases normally but progesterone decreases, you should go to the hospital in time to check whether the fetal development is normal and whether there is fetal arrest. In addition, if the corpus luteum is insufficient, it may easily cause threatened abortion or fetal development arrest. At this time, you should supplement natural progesterone in time, and of course go to the hospital for a good diagnosis in time. The HCG blood test is currently the earliest and most accurate way to test whether a woman is pregnant. The HCG blood test is usually done 8-10 days after sexual intercourse to determine whether a woman is pregnant by drawing blood to test for HCG. Human chorionic gonadotropin (hCG) is a glycoprotein secreted by trophoblast cells of the placenta and is composed of two subunits, a- and b-. hCG enters the maternal blood after fertilization and proliferates rapidly until the 8th week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains stable. The HCG blood test is a quantitative test of HCG in the blood to understand whether pregnancy is possible. Blood HCG early pregnancy test (human chorionic gonadotropin) is the "pregnancy test" hormone that is familiar and most commonly used by obstetricians and gynecologists. It is composed of glycoproteins of α and β dimers. When a woman becomes pregnant, HCG will be present in her blood and urine. There are still many errors in the accuracy of early pregnancy test strips. When women do self-pregnancy tests at home, they are done without professional guidance, and the test results are generally only 75% accurate. If the test is performed under the guidance of a doctor, it can ensure the correct use of the early pregnancy test paper and the test accuracy will be higher. |
