What is full form of GA in pregnancy?

Infants born before 37 weeks are considered premature.
Is AUA more accurate than LMP?
When ultrasound was used instead of certain LMP, the number of postterm pregnancies decreased from 10.3% to 2.7% (P <. 001). Conclusion: Ultrasound was more accurate than LMP in dating, and when it was used the number of postterm pregnancies decreased.
