Determining gestational age involves calculating the number of weeks elapsed since the first day of the last menstrual period. This calculation provides an estimation of how far along a pregnancy has progressed. For example, if the first day of the last menstrual period was January 1st, and the current date is February 5th, the calculation would indicate a gestational age of approximately 5 weeks.
Accurate determination of gestational age is crucial for several aspects of prenatal care. It allows healthcare professionals to monitor fetal development appropriately, schedule relevant screening tests at optimal times, and anticipate the expected delivery date. Historically, this calculation provided a foundational tool for managing pregnancy, enabling better-informed decisions regarding interventions and delivery methods. Its precision contributes significantly to improved maternal and neonatal outcomes.
