FAQ

What growth standards are used for percentiles?
Calculations reference the WHO growth charts for infants 0-2 years and the CDC 2000 growth charts for children 2-20 years.
How is pediatric drug dosage verified?
Doses are calculated per kilogram of body weight (mg/kg/dose or mg/kg/day) and capped at maximum adult recommended dosages to ensure therapeutic safety.
Can pediatric tools replace direct clinical care?
No. Pediatric screening tools assist healthcare providers and parents, but prescription dosing and emergency management must be confirmed by a qualified pediatrician.
