Full Form of EGA
What is EGA?
Estimated Gestational Age (EGA) is a critical measurement in obstetrics used to determine how far along a pregnancy has progressed. It is typically calculated from the first day of the last menstrual period (LMP) or via ultrasound measurements such as crown-rump length in early pregnancy. In India, EGA is routinely assessed during antenatal visits in both public health centres and private clinics to monitor fetal development, schedule necessary tests like anomaly scans and glucose tolerance tests, and plan delivery dates. Accurate EGA helps in identifying high-risk pregnancies, such as those that are preterm or post-term, and guides decisions on interventions. For medical students and residents preparing for exams like NEET PG and AIIMS, understanding EGA calculation and its clinical importance is essential. It is also used in research to track pregnancy outcomes across different regions of India. The term is encountered in hospital records, ultrasound reports, and maternal health programmes like Janani Suraksha Yojana, ensuring uniform communication among healthcare providers.

EGA — frequently asked questions
What is the full form of EGA?
EGA stands for Estimated Gestational Age, which indicates the age of a fetus based on the first day of the last menstrual period or ultrasound measurements.
How is EGA calculated in India?
EGA is calculated either by counting weeks from the last menstrual period (LMP) or by using ultrasound parameters like crown-rump length (CRL) in early pregnancy, with the latter being more accurate.
Why is EGA important for pregnancy care?
EGA helps track fetal growth, schedule prenatal tests, predict the due date, and identify risks such as preterm or post-term pregnancy, ensuring timely medical interventions.
