  1. Hello Dear,

    Thank you for writing to us at MediMetry.

    AFI between 8-18 cm is considered normal; median AFI level is ~14 cm from week 20 to week 35, after which the amniotic fluid volume begins to reduce AFI 20-24 cm is considered as polyhydramnios
    The normal range for amniotic fluid volumes varies with gestational age. As a rule of thumb:
    AFI of 25 implies polyhydramnios. So at 37 week AFI 8-9 is normal.

    Hope this answers your query. Feel free to write back to us with follow-up questions.
