Key facts

Fetal Body weight Estimated
Body weight
Fetal body weight is an important measurement variable for assessing both fetal and maternal health. There are many different methods for estimating fetal body weight, including ultrasound, fetal palpitation, and formulas based on various maternal measurements, such as fundal height. Variables that influence the accuracy of body weight estimation include whether the fetus is within the normal range for body weight given its gestational age, maternal body mass index, and the skill of the clinician estimating the weight. Ultrasound may be the most reliable method for estimating fetal body weight at term if the technology and an experienced ultrasonographer is available. [PMID28392581]
