Siemer et al reported an equation for estimating the body weight of a fetus weighing <=2,500 grams. The authors are from University Hospital Mannheim.
Patient selection: weight less than 2,500 grams, exam performed less than 7 days from delivery
Parameters:
(1) abdominal circumference in cm (AC)
(2) femur length in cm (FL)
(3) biparietal diameter in cm (BPD)
estimated fetal weight in grams =
= (2101.261 * LN(AC)) + (15.613 * ((FL)^2)) + (0.577 * ((BPD)^3)) - 5948.336
