The information should not be construed as dictating an exclusive course of treatment or procedure to be followed.

Subsequent changes to the EDD should be reserved for rare circumstances, discussed with the patient, and documented clearly in the medical record. When determined from the methods outlined in this document for estimating the due date, gestational age at delivery represents the best obstetric estimate for the purpose of clinical care and should be recorded on the birth certificate. For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the last menstrual period alone, should be used as the measure for gestational age.

For instance, the EDD for a pregnancy that resulted from in vitro fertilization should be assigned using the age of the embryo and the date of transfer.

The role of ultrasonography in obstetric practice has continuously evolved since its introduction more than 40 years ago. Indeed, it is difficult to imagine a modern obstetric practice without access to the information provided by real-time ultrasound. Using this imaging technique, clinicians can detect pregnancy as early as 3 weeks after conception, confirm or revise gestational age with reasonable accuracy, diagnose multiple gestation in early pregnancy, confidently diagnose fetal death at any gestational age, assess fetal well-being, evaluate amniotic fluid volume, and diagnose a broad variety of fetal malformations.
