When to Use

Primary Clinical Uses

Distinguishing pathological Fetal Growth Restriction (FGR) from constitutionally small-for-gestational-age (SGA) fetuses

Standardizing research definitions and clinical triaging for growth abnormalities globally

The Paradigm Shift

Historically, any fetus <10th percentile was labeled FGR. The Delphi consensus establishes that FGR is a trajectory/functional issue. A fetus dropping dramatically from the 70th to 15th percentile may be highly restricted, while a genetically healthy 8th percentile fetus is merely SGA.
