GESTATION LENGTH IN WEEKS

This is the number of weeks completed gestation, based upon an average 40 week gestation, which may be derived from:

a)estimated date of delivery calculated by Ultrasound Scan measurements according to the trimester of the scan
b)estimated date of delivery measured from the first day of last menstrual period (LMP)
c)clinical assessment (in the absence of a or b) - antenatally for Maternity, postnatally for Neonatal

The gestational age should be recorded in completed weeks: e.g. events occurring 280-286 days after the onset of the last menstrual period are considered to have occurred at 40 weeks gestation.
