Pregnant women can still have prenatal checkups without a card, but if they don’t have a card, they should know that they need to have ultrasound, routine blood tests, blood type and liver and kidney function tests, blood sugar and lipid tests, the four eugenics tests and infectious disease tests in early pregnancy. In addition, ultrasound examinations should be performed from 11 to 13 weeks of pregnancy to understand the development of the fetus and NT value; Down’s syndrome screening should be performed from 14 to 19 weeks; 4D ultrasound examination and diabetes screening should be performed around 24 weeks, and so on. Pregnant women worry a lot, but after establishing a perinatal health card, they can record the relevant examinations during pregnancy through the perinatal health card throughout pregnancy, and provide valuable medical reference information for doctors after admission to hospital or during hospital delivery. If you can’t have your pregnancy checkup at a fixed hospital, the perinatal health cards of different hospitals can be used together, so you can bring them with you every time you come for your maternity checkup, and you don’t need to bring more health cards from different hospitals.
