Pregnancy tests generally include urine pregnancy test, ultrasound, Down’s syndrome, fetal heart monitoring and so on. 1. Urine pregnancy test: urine pregnancy test during early pregnancy can detect whether a woman is pregnant or not. 2. Ultrasound: Ultrasound can be used to determine whether the pregnancy is intrauterine or extrauterine and to detect the development of the fetus. 3. Down’s syndrome screening: The serum of the pregnant woman can be taken to detect the concentration of certain substances in her mother’s serum, and the risk factor of giving birth to a baby with birth defects can be calculated by taking into account the expected date of birth, weight, age and the gestational cycle of the pregnant woman at the time of blood collection. 4. Fetal heartbeat monitoring: In late pregnancy, pregnant women need to do regular fetal heartbeat monitoring, and they can also count the movement of the fetus at home. In clinical practice, it is recommended that pregnant women should have regular pregnancy checkups and go to the hospital in time if they are not feeling well, so as to avoid any danger in the process of childbearing.
