How to diagnose SGA if dates are unknownIf dates are unknown, serial sonographic examinations at two-week intervals should be performed to evaluate the rate of interval growth (ie, growth velocity). Irrespective of GA, there is a significantly lower rate of change over time of AC or EFW in FGR fetuses compared with those fetuses whose growth is appropriate for GA [81]. In one study, as an example, a change in fetal AC of less than 10 mm over a two-week period had a sensitivity of 85 percent and specificity of 74 percent for identifying FGR How to diagnose SGA if date is unknownnormal singleton fetal growth increases from approximately 5g/dayat 14 to 15 weeks of gestation to 10g/dayat 20 weeks and 30 to 35g/dayat 32 to 34 weeks, after which the growth rate decreases
