About this calculator
The Ultrasound DPP Calculator (CCN) is an online tool that helps to calculate the estimated due date (EDD) based on the ultrasound of the fetal blood flow in the umbilical cord (CCN).
The calculation is done using the formula: DPP ≈ date_US + (280 - IG_US), where date_US is the date of the ultrasound and IG_US is the estimated gestational age. This tool is useful for doctors and patients who need to know the estimated due date.
It's worth noting that ultrasound is a reliable method for estimating gestational age, but the actual due date can vary due to various factors. Therefore, this calculator should be used only as a supporting tool and not as a definitive diagnostic method.
