Prenatal age-specific reference intervals for measuring all five digits of the fetal hand.

Objective: To construct prenatal age-specific reference intervals for measurement of five digits in normal fetuses.

Patients And Methods: Prospective cross-sectional study of fetuses assessed at an antenatal ultrasound unit in a university-affiliated general hospital. The study cohort comprised 302 pregnant women attending our clinic for routine fetal biometry or anomaly scan between December 1997 and June 2000.
