The normal amount of amniotic fluid in a pregnant woman is between 300 and 2000 ml. The ultrasound room gives a few values of amniotic fluid during the maternity test, it does not have a specific amount of amniotic fluid. the ultrasound results usually have two values of amniotic fluid. The first one is the maximum depth of the amniotic fluid. The second is the amniotic fluid index. The normal value of the amniotic fluid index is 8-18 cm, and the normal amniotic fluid of a pregnant woman is reflected in these two values on the ultrasound. If the value is not within the normal range, consider the case of abnormal amniotic fluid.
