Various tests during pregnancy

From the time a woman is diagnosed with pregnancy, she may go to the hospital the most times in her life. Prenatal checkups during pregnancy are a manifestation of responsibility for the child and the mother. There are slight differences in the examinations and focuses performed at different times during pregnancy. For example, in the early stages of pregnancy, the main focus is on whether the fetus is stable and whether the mother has some genetic diseases. In the middle of pregnancy, what needs to be checked is whether the fetus has any deformities.

In the early stages of pregnancy, that is, from the 1st to the 12th week of pregnancy, the main procedures include: B-ultrasound examination, which can rule out ectopic pregnancy, observe the development of the fetus, and measure the size of the fetus; check for pathogens that cause intrauterine infection, mainly to see whether the baby has been infected with rubella virus, cytomegalovirus, Toxoplasma, herpes simplex virus, etc.; screening for hepatitis virus, which can cut off mother-to-child transmission of the virus as early as possible; routine blood and urine tests to check for anemia, blood diseases, and urinary system diseases.

In the second trimester, which is from the 13th to the 27th week of pregnancy, the main things to do are: a color B-ultrasound examination around the 22nd week of pregnancy can give a comprehensive understanding of the development of the fetus in the uterus and rule out fetal malformations; a sugar screening is performed at the 24th to 28th week of pregnancy. If the screening is positive, a further glucose tolerance test is performed to detect pregnancy complicated with diabetes as early as possible and whether the patient has gestational diabetes; an MP measurement should be performed at the 20th week of pregnancy to predict whether there is a tendency for pregnancy-induced hypertension syndrome; and a Down syndrome (congenital idiocy) screening is performed at the 16th to 20th week of pregnancy.

In the late pregnancy, that is, from the 28th week of pregnancy to delivery, the main things to do are: fetal monitoring with a fetal monitor starting from the 32nd week, preferably once a week, to observe and record the dynamic changes in fetal heart rate, and to predict the fetal intrauterine reserve capacity; umbilical cord blood flow test, to detect the resistance of fetal umbilical cord blood flow, to understand whether there is intrauterine hypoxia; B-ultrasound examination, to understand the maturity of the placenta, the amount of amniotic fluid and the growth and development of the fetus; blood type, four coagulation tests, renal function, and liver function tests are performed at 36 weeks to prepare for delivery.
