Fetal growth percentile
Statistical ranking of fetal size measurements compared to gestational age-specific reference ranges.
Full Definition
Fetal growth percentile represents where a fetus's biometric measurements fall within the distribution of normal measurements for a given gestational age, typically expressed as a percentage from 1st to 99th percentile. Measurements below the 10th percentile may indicate intrauterine growth restriction, while those above the 90th percentile suggest macrosomia. These percentiles are calculated using standardized growth charts and are essential for identifying fetuses at risk for adverse outcomes and guiding clinical management decisions.
Usage
Usage note: Always specify which growth chart reference was used for percentile calculations.
