Online published on 18 December, 2015. Abstract The study was carried out to assess fetal gestational age with the help of ultrasonographic measurements of different fetal biometric parameters [i.e. Biparietal diameter (BPD), Femur length (FL), Abdominal circumference (AC)] and Fetal kidney width (KW), in 199 women with singleton uncomplicated pregnancies attending the O.P.D for routine ultrasound fetal biometry in western Uttar Pradesh (UP). Above fetal parameters were measured biweekly, between 18 and 38 weeks of gestation. Linear regression models for estimation of gestational age were derived from above fetal biometric parameters. The linear regression model for estimating fetal gestational age is femur length, abdominal circumference, fetal kidney width and biparietal diameter in that order with standard error of ± 3.85, ± 4.85, ± 5.81 and ± 8.75 days respectively.
