estimated fetal weight percentile
Statistical ranking of fetal weight compared to population norms for gestational age.
Full Definition
A percentile ranking that compares the estimated fetal weight to established population reference curves for the same gestational age. Percentiles below the 10th are often considered small for gestational age, while those above the 90th may indicate macrosomia. Different growth charts may be used depending on population characteristics and clinical protocols. The percentile helps clinicians assess whether fetal growth is appropriate and guides decisions about monitoring intensity and delivery timing.
Usage
Usage note: Use 'percentile' rather than 'centile' in American medical writing; both are acceptable in international contexts.
