How to assess GESTATIONAL AGE via US?
1st trimester—-> Gestational sac diameter
1st and 2nd—-> Crown rump length
2nd and 3rd—-> Biparietal diameter / head circumference/ femur length
Important point of gestational age assessment
If USG during 2nd and 3rd trimester shows discrepancy between EGA (calculated from 1st trimester crown rump length) and fetal measurements, growth problems should be considered (e.g. fetal macrosomia, fetal growth restriction)
Define Anemia in pregnancy
Anemia in pregnancy defined as: Hb <11 g/dl in 1st and 3rd trimester and <10.5 g/dl in 2nd trimester
