How to calculate a baby's weight in the womb

A baby's weight in the womb is determined using a fetal growth curve, which is a standardized developmental chart that helps doctors assess the fetus's health. According to the fetal growth curve, a baby's weight can be estimated through regular endoscopic examinations of the uterine cavity or via ultrasound scans. Endoscopic examination allows assessment of the baby's size, shape, and weight, while ultrasound can measure the baby's weight and abdominal circumference. Additionally, the baby's weight in the womb can also be estimated through regular blood tests, which measure the fetus's hemoglobin levels to help approximate its weight.
