About Fetal Growth Chart

Fetal Growth Chart is a free web-based tool for the graphical assessment of fetal biometry and estimated fetal weight, built for clinicians who plot serial growth scans.

Who made it

The tool was developed by Dr Mohamad Sahir bin Zulkifli of the Obstetrics & Gynaecology Department, Hospital Tanah Merah, Kelantan, Malaysia. It started as a way to plot serial growth scans quickly and consistently in a busy antenatal clinic, without redrawing paper charts at every visit, and was then made available to other clinicians as a public, session-only website.

Features

• Singleton and twin pregnancies, with chorionicity and twin identification
• Up to five serial measurements of BPD, HC, AC, FL and EFW
• WHO centile band shown for every value in the history table
• AFI for singleton pregnancies, DVP for each twin
• Umbilical artery Doppler status and indices, fetal heart, placenta and remarks
• Automatic twin EFW discordance
• Edit and delete individual measurements, with checks for common entry errors
• Printable A4 report with blank fields for handwritten patient details

Accuracy

The centile curves are generated from the published WHO coefficients. We checked the curves against the WHO reference tables (Kiserud et al. 2017) for all five parameters and five centiles at 14, 20, 28, 36 and 40 weeks: all values match the published tables after rounding.

Independent implementation

The website uses mathematical fetal growth references derived from the published WHO fetal growth study. Fetal Growth Chart is an independent implementation and is not an official WHO application.

Data handling

There is no patient database, patient account or patient search. Patient names and ID numbers are not entered into the website. Measurements stay in the current browser tab only. See the Privacy Statement.
