Fetal Growth Projection is simply the best Obstetrics calculator available on the market. Developed by Chang L Lee MD Inc, a practicing OBGYN, this application has been clinically tested to ensure accuracy and reliability.

The app offers a range of features to assist healthcare professionals in their obstetric practice. The Rapid Gestational Age Calculator allows practitioners to enter the due date in just a few taps. With 8 date pickers, each a month apart, users can easily select the desired month and day to complete the input.

Another valuable feature is the Fetal Weight Percentile calculator, which provides weight percentiles from two sources to enhance clinical decision-making. The percentile information is calculated using error functions and z-scores, with a primary focus on the 10th percentile. Additionally, the app provides a weight projection at 39 weeks, offering a better understanding of percentiles.

The Final Estimated Due Day feature allows physicians or assistants to establish the final estimated due date based on the first day of the last menstrual period, date of ultrasound, and gestational age. This calculation follows the guidelines of the American College of Obstetricians and Gynecologists (ACOG).

Lastly, the app includes a Weight Conversion tool that allows for easy conversion between grams and pounds. This is particularly useful as ultrasounds often provide weight estimates in grams. The tool saves time and eliminates the need for manual calculations.

It's important to note that Fetal Growth Projection is an educational tool and should not be used as medical or treatment advice. Users are encouraged to consult with their physician or healthcare practitioner for any medical diagnosis or treatment recommendations.
