What are the examination items at each stage of pregnancy?

Pregnancy check-up is a series of examinations that women must undergo during pregnancy. It is an important part of giving birth to a healthy baby. From pregnancy to delivery, expectant mothers will go through various pregnancy check-ups, hoping to discover problems in time through these examinations to ensure the birth of a healthy and strong baby. So, what are the examination items at each stage of pregnancy? We have specially compiled this detailed content for reference by expectant mothers.

Pregnancy check-ups are mainly divided into three stages: early pregnancy, mid-pregnancy and late pregnancy, and different examination items are involved in these three stages.

In the early stages of pregnancy, that is, from the 1st to the 12th week of pregnancy, the main tasks include: ① B-ultrasound examination, which can rule out ectopic pregnancy, observe the development of the fetus, and measure the size of the fetus; ② Check whether there are pathogens that cause intrauterine infection, mainly to see whether there has been infection with rubella virus, cytomegalovirus, Toxoplasma, herpes simplex virus, etc.; ③ Screening for hepatitis virus, which can cut off mother-to-child transmission of the virus as early as possible; ④ Routine blood and urine examination to check whether there is 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: ① A color B-ultrasound examination is performed around the 22nd week of pregnancy to fully understand the development of the fetus in the uterus and rule out fetal malformations; ② A sugar screening is performed at 24-28 weeks 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; ③ MP determination should be performed at 20 weeks of pregnancy to predict whether there is a tendency for pregnancy-induced hypertension syndrome; ④ Down syndrome (congenital idiocy) screening is performed at 16-20 weeks of pregnancy.

In the third trimester, that is, from the 28th week of pregnancy to delivery, the main things to do are: ① fetal monitoring with a fetal monitor starting from the 32nd week, preferably once a week, which can observe and record the dynamic changes of the fetal heart rate and predict the fetal intrauterine reserve capacity; ② umbilical cord blood flow examination, which can detect the resistance of the fetal umbilical cord blood flow and understand whether there is intrauterine hypoxia; ③ B-ultrasound examination, which can understand the maturity of the placenta, the amount of amniotic fluid and the growth and development of the fetus; ④ blood type, four coagulation tests, renal function, and liver function tests at 36 weeks, which are preparations for delivery.

The above are the examination items for each stage of pregnancy. Prenatal check-up is a very important part during pregnancy, so pregnant mothers must have a scientific and correct understanding of this. In addition to allowing you to understand your own health status before pregnancy, it focuses on detecting high-risk factors related to pregnancy, conducting pre-pregnancy intervention and eugenics guidance, which is of great significance to reducing the birth defect rate and maternal mortality rate and improving the quality of the population.
