Fasting monitoring is not required for pregnancy checkups, except for the first maternity checkup for liver and kidney function and diabetes. The main methods of nutritional testing during pregnancy include: routine blood test for anemia; trace elements test for iron, calcium, zinc, iodine, selenium, potassium, etc.; ultrasound test for fetal biparietal diameter, head circumference, femur length or regular measurement of maternal uterine height and abdominal circumference for discrepancy with gestational week, etc. All of them can be tested after normal diet without fasting.
