The 34th week of pregnancy indicates that you have entered the late stage of pregnancy, and at the same time, the labor and delivery test also seems to be crucial. 34 weeks of labor and delivery test routine items usually do not need to be performed on an empty stomach, but there are some special circumstances that need to be examined in an empty stomach state. Prenatal checkups at 34 weeks include measurement of blood pressure, pulse, weight, uterine height and abdominal circumference. Routine blood and urine tests are also required if they have not been done within a month. Fetal 3D ultrasound, or mini-detectoral ultrasound, is also required at 34 weeks, and none of the above tests need to be performed on an empty stomach. In addition, fetal heart monitoring does not require an empty stomach, because an empty stomach may lead to poor responsiveness of fetal heart monitoring. It is recommended that pregnant women bring a small amount of snacks and some drinking water with them to eat during fetal heart monitoring. If the pregnant woman has not had a glucose tolerance screening test, liver and kidney function or thyroid function test during pregnancy, she needs to keep fasting. Pregnant women are advised to go to the hospital as early as possible for laboratory tests to avoid fainting caused by fasting for too long. If a pregnant woman is particularly hungry, the fetus in the womb may also suffer from hypoglycemia, which may lead to slowing down of the fetal heart. In addition, it is recommended that pregnant women should pay close attention to monitoring the fetal movement and have another delivery test 2 weeks later.
