Normal afi values range from 5 to 25 cm values the normal range for amniotic fluid volumes varies with gestational age. An afi of less than 5 to 6 centimeters leads to a condition called oligohydramnios, which means that amniotic levels are low. The pocket with the largest vertical dimension is measured in each quadrant.
