AU Gestational Age Profile [FMM Level 0]

This profile is provided as a common representation of gestational age related to pregnancy. This may include specific observation of gestational age by scan, or gestational age by last menstrual period (LMP).

Usage Notes

  • Used to record an gestational age at a point in time.
