gestational age
The age of a developing baby measured from the first day of the mother's last menstrual period.
Full Definition
A measure used to describe how far along a pregnancy has progressed, calculated from the first day of the woman's last menstrual period (LMP) rather than from conception. Expressed in weeks and days (e.g., 38 weeks and 2 days), gestational age is crucial for determining appropriate medical care, timing of delivery, and assessing newborn maturity. Term delivery occurs between 37-42 weeks gestational age, while babies born before 37 weeks are considered preterm and those born after 42 weeks are post-term.
Usage
Usage note: Always specify in weeks and days when possible; distinguish from postmenstrual age in ongoing care.
