3.2 Normal growth

The charts delineate the optimal growth rate in each pregnancy, to the ‘term optimal weight’ which the software determines by customising according to the physiological characteristics of each mother in each pregnancy. 

The SFH measurements plotted here illustrate that the growth rate is normal.
NB: The rate can be normal even if the actual values are not within normal limits (10th and 90th centile lines).

SFH measurements should be recorded to one decimal place e.g. 27.8cm
