## What is Birth Weight Percentile?

Specialized Birth Weight Percentile Calculator for Neonatal Care
This app is uniquely designed for healthcare professionals specializing in neonatal care, such as pediatricians and neonatologists. Unlike general growth charting apps, it focuses solely on calculating birth weight percentiles with unmatched efficiency and precision.

Key Features:

    Instantly calculate birth weight percentiles for preterm and full-term newborns.
    Tailored for neonatal care with precise inputs: gestational weeks, days, sex, and birth weight.
    Visualize percentile results in an easy-to-understand format, enabling rapid clinical decision-making.
    Reference data sourced from the groundbreaking study:
    "A Revised Birth Weight Reference for the United States" by Duryea EL, et al., published in American Journal of Obstetrics & Gynecology (Elsevier), Volume 219, Issue 4, Pages 408.e1–408.e9, October 2018. Licensed through Wolters Kluwer Health, Inc.

Why This App is Unique:
Unlike other apps that track longitudinal growth or general development trends, this app is designed for rapid and accurate assessment of birth weight at the point of care. It allows healthcare professionals to quickly classify newborns into:

    SGA (Small for Gestational Age): Below the 10th percentile
    AGA (Appropriate for Gestational Age): Between the 10th and 90th percentiles
    LGA (Large for Gestational Age): Above the 90th percentile

This classification is crucial for identifying potential medical conditions associated with growth abnormalities. The app’s quick and intuitive interface ensures healthcare providers spend less time on calculations and more on patient care.

Intended Audience:
This app is a vital tool for neonatal and pediatric healthcare professionals working in NICUs, newborn nurseries, and other clinical settings. It is not a general growth tracking app for parents or caregivers but a specialized resource for medical decision-making.
