2. Diagnosis of Low Amniotic Fluid

An ultrasound or amniotic fluid index (AFI) can measure the volume of amniotic fluid in the womb. Doctors confirm a diagnosis of oligohydramnios when the AFI shows fluid levels under five centimeters. Other factors that indicate oligohydramnios are the absence of a fluid pocket two or three centimeters deep, or less than 500 milliliters of total fluid volume between 32 to 36 weeks of pregnancy. Medical professionals measure fluid pockets where the amniotic fluid has maximum depth in a clear area not occupied by the umbilical cord or any part of the baby.
