1st check
★ 5-8 weeks
Required items:
1. Ultrasound examination of early pregnancy (to determine intrauterine pregnancy and gestational age, whether the fetus is alive, the number of fetuses and the attachments of the uterus).
2. Blood routine/coagulation function/serum ferritin (hemoglobin <110 g/L) / urine routine / blood type (ABO and Rh) / ELECTROCARDI / liver and kidney function (fasting) / lipid / fasting blood glucose / hepatitis B 2-and-a-half / HIV and syphilis screening / thyroid function measurement; OGTT test for high risk factors of preconception diabetes mellitus (PGDM); thalassemia screening; TORCH test (no passage before pregnancy).
2nd check
★ 11-13+6 weeks
1. Fetal color ultrasound - NT value determination (fetal neck zona pellucida thickness screening).
2. Cervical cytology examination (those who have not been checked in the first 12 months of pregnancy).
First Trimester Preparation:
Cardiac ultrasound, cervical secretions detection of gonococcus and Chlamydia trachomatis (high-risk pregnant women or symptomatic), detection of bacterial vaginosis (BV) (symptomatic or preterm birth), HCV screening, anti-D titer (Rh negative);
· PPD testing for pregnant women at high risk of TB (artificially inseminated women, areas with a high incidence of tuberculosis, poor living conditions, HIV infection, drug addicts);
Maternal serological screening of fetal chromosomal aneuploidy abnormalities at 10-13+ 6 weeks gestation (pregnancy-related plasma proteinS A and free β-hCG);
People with high-risk factors are given necessary prenatal screening or other tests with medical indications.

6th check
★ 29-32 weeks
1. Routine inspection.
2. Fetal ultrasound (screening for fetal growth restriction).
7th check
★ 32-34 weeks
1. Routine examination (once a week after 36 weeks).
2. Fetal heart rate monitoring (once a week after 37 weeks).
3. Hematuria routine, liver and kidney function, blood lipids, serum bile acids, electrolytes, hepatitis B two-and-a-half, HIV and syphilis screening.
4. If anemia is complicated, serum ferritin should be checked regularly according to the actual situation.
5. High Risk Score.
8th check
★ 38 weeks
2. Fetal ultrasound.
3. Assessment (with or without head basin).
4. Fetal heart rate monitoring.
Items to be investigated in the third trimester of pregnancy:
Electrocardiogram examination;
Placental function test;
Ratio of umbilical artery systolic peak to terminal diastolic flow rate (S/D ratio) detection;
Pregnant women with high risk factors (such as comorbid diabetes mellitus, newborns born in the previous pregnancy with GBS infection, etc.) are screened for group B streptococcus (GBS);
Cervical examination and Bishop score, and appropriately increase the number of examination items when the condition is needed.
Regular obstetric check-ups
It is an important guarantee for the health of pregnant mothers and fetuses, and the feelings of pregnant mothers are also very important.
