Common questions
Which reference standard is used?
The built-in model is an approximate fit to the magnitudes in Hadlock 1984 and similar sources and has not been checked week by week against a single standard, so percentiles are approximate. Use your unit's reference (e.g. INTERGROWTH-21st or Hadlock). Values more than 5 SD from the mean are rejected.
When should I use Fetal Biometry Percentile?
Enter gestational age and a fetal measurement (BPD/HC/AC/FL/transverse cerebellar diameter) to estimate its percentile, helping judge whether growth deviates from the normal range.
