Guide for use:Help on this term

This is derived from clinical assessment when accurate information on the date of the last menstrual period is not available for this pregnancy.

Gestational age is frequently a source of confusion when calculations are based on menstrual dates. For the purposes of calculation of gestational age from the date of the first day of the last normal menstrual period and the date of delivery, it should be borne in mind that the first day is day zero and not day one.
