The first pregnancy test is not a lot of items, and the content is not complicated, usually some basic tests, first of all, the first pregnancy test needs to draw blood, first of all, to check the value of HCG in the blood, to determine whether the pregnancy, in addition to check the level of progesterone in the body, if the progesterone is low, there is a possibility of preterm abortion. Next, a pelvic 3D ultrasound is performed to confirm if the pregnancy is intrauterine and if there is a fetal heartbeat and fetal buds in the intrauterine cavity to determine the week of pregnancy and project the expected date of delivery. If a woman’s menstrual cycle is regular, the expected date of delivery can be calculated according to the usual method. Generally, the date plus 7 days, the month minus 3 or plus 9 is the expected date of delivery. If a woman’s menstrual cycle is irregular, the week of pregnancy should be further deduced based on the time of early pregnancy reaction, the time of intercourse, and the size of the fetal bud measured by ultrasound. Some routine laboratory tests are also needed, including routine blood tests, blood type, urine routine, fasting blood sugar, liver function, kidney function, hepatitis B surface antigen, syphilis serum antibody screening and HIV screening. In addition, if the pregnant woman has thyroid-related diseases before pregnancy, she also needs to have a thyroid function screening and, if necessary, an ultrasound of the thyroid gland at the first pregnancy test. The pregnant woman’s blood pressure and weight should also be measured and the body mass index calculated. If the body mass index is >30, the woman is considered obese, and for particularly obese women, a 75g glucose tolerance test is recommended to confirm the presence of diabetes. During pregnancy, attention is paid to monitoring blood pressure and blood glucose to avoid hypertensive disorders of pregnancy and gestational diabetes. The doctor will assess whether the pregnant woman has high-risk factors, and if there are high-risk factors, she needs to go to a prenatal diagnosis center for prenatal checkups.
