The blood test in early pregnancy mainly looks at the values of human chorionic gonadotropin (HCG) and progesterone.
1. HCG: HCG can be detected in the blood on the sixth day after fertilization. If the HCG is less than 5 mIU/ml, it means that you are not pregnant; if it is more than 10 mIU/ml, it means that you are pregnant. If the value is greater than 10mIU/ml, it means that you are pregnant. And the value increases exponentially, which means that the fetus is growing and developing well in the uterus.
2. Progesterone: its value can reflect the situation of progesterone in the body, which mainly plays a role in thickening the uterine lining and facilitating the fertilization of the egg. If the progesterone is lower than 20ng/ml after pregnancy is diagnosed, it means that the embryo is underdeveloped in the uterus and is prone to miscarriage with precocious abortion, so it is necessary to preserve the fetus under the guidance of the doctor.
