AGA
Also written as: AGA — Appropriate for Gestational Age
Appropriate for gestational age; birth weight between the 10th and 90th percentiles for gestational age.
Full Definition
Appropriate for gestational age (AGA) describes infants whose birth weight falls between the 10th and 90th percentiles for their gestational age according to standardized growth charts. These infants have experienced normal intrauterine growth patterns and typically have lower risks for immediate postnatal complications compared to SGA or LGA infants. AGA classification is an important indicator of fetal well-being and helps guide initial clinical management and risk stratification.
Usage
Usage note: Use with gestational age context; not synonymous with 'normal' birth weight.
