The national livelihood program stipulates that pregnant women should go to the appropriate community to establish a pregnancy test book and complete the first maternity checkup. The first maternity checkup is free of charge for tests such as routine blood, ABO blood group, hepatitis B surface antigen, liver and kidney function. The subsequent maternity tests, such as uterine height, abdominal circumference, and listening to the fetal heart, are also free of charge, and these items need to be completed in the designated community. This is to ensure the safety of the fetus and the mother to the greatest extent possible.
