WARNING:
The gestational age calculated by
your SonoSite system does not
match the age in the
aforementioned reference at the
20.0 cm and 30.0 cm abdominal
circumference (AC) measurements.
The implemented algorithm
extrapolates the gestational age
from the slope of the curve of all
table measurements, rather than
decreasing the gestational age for a
larger AC measurement indicated in
the referenced table. This results in
the gestational age always
increasing with an increase in AC.
