This is the W.H.O definition for length of gestation in completed weeks. Measured from the first day of the last menstrual period (LMP) where this is thought to be reliable. For the remainder a best estimate based on likely LMP and ultrasonic measurement is to be recommended. Gestational age is expressed in completed weeks, e.g. events occurring to 280 days to 286 days after the onset of the last menstrual period are considered to have occurred at 40 weeks gestation.
