Up to and including 13 6/7 weeks of gestation, gestational age assessment based on measurement of the crownârump length (CRL) has an accuracy of Â± 5â7 days (11â14). Measurements of the CRL are more accurate the earlier in the first trimester that ultrasonography is performed (11, 15â18).linical Considerations in the Third Trimester Gestational age assessment by ultrasonography in the third trimester (28 0/7 weeks of gestation and beyond) is the least reliable method, with an accuracy of Â± 21â30 days (19, 20, 23).
