gestational age
Noun: * The age of an embryo or fetus, measured in weeks from the first day of the woman's last menstrual period (LMP) to the current date. This is the standard medical method for dating a pregnancy, as the exact date of fertilization is often unknown. Gestational age is a crucial indicator for monitoring fetal development and determining the expected date of delivery.
Gestational age is a clinical term used primarily in obstetrics, pediatrics, and prenatal care to assess the stage of a pregnancy or the maturity of a newborn. * It is typically expressed in completed weeks (e.g., 12 weeks, 39 weeks). * A full-term pregnancy is approximately 40 weeks of gestational age. * It is distinct from fetal age (or conceptual age), which is measured from the estimated time of fertilization and is about two weeks less.
