3.4 Slow Growth (SFH)

Example of SLOW GROWTH suspected from SFH  measurements. This is defined as the slope or growth rate between measurements which is slower or flatter than the slope of the 10th centile line over the same gestational age interval, as shown on the graph.  

A demonstration of how to make this comparison using a set square is available here. 

‘Slow growth’ includes ‘no’ or ‘static’ growth. It is an indication for referral for scan.
