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.
