Multiple fetal weight estimation formulas exist. Below are seven commonly used obstetric formulas, each with an approximate 8% margin of error. These serve as general references for expectant parents!
Birth weight is likely a significant factor influencing neonatal mortality.
Predictive Formula 1: Fetal Weight (g) = 260.69 × HC (Head Circumference) - 4973.72
Predictive Formula 2: Fetal Weight (g) = 171.48 × AC (Abdominal Circumference) - 2686.60
Predictive Formula 3:Fetal Weight (g) = 747.42 × FL (Femur Length) - 2232.56
Predictive Formula IV: Fetal Weight (g) = 1049.90 × FTH (Fetal Thigh Subcutaneous Fat Thickness) - 2513.51
Predictive Formula V:Fetal Weight (g) = 100.97 × HC (Head Circumference) + 110.86 × AC (Abdominal Circumference) + 143.09 × FL (Femur Length) + 331.43 × FTH (Fetal Thigh Subcutaneous Fat Thickness) - 5168.32
Predictive Fetal Weight Formula 6:Fetal Weight (g) = 900 × BPD (Biparietal Diameter) - 5200
Predictive Fetal Weight Formula 7: Fetal Weight (g) = 0.3 × Fundal Height × Circumference 2900
