An AFI between 8-18 is considered normal. Median AFI level is approximately 14 from week 20 to week 35, when the amniotic fluid begins to reduce in preparation for birth. An AFI < 5-6 is considered as oligohydramnios. The exact number can vary by gestational age.

What happens if AFI is high?

Women with polyhydramnios may experience premature contractions, longer labor, difficulties breathing, and other problems during delivery. The condition can also cause complications for the fetus, including anatomical problems, malposition, and, in severe cases, death. Treatment aims to remove excess amniotic fluid.

What should be AFI at 34 weeks?

From 34 weeks through to labor, the fluid decreases to about 400 ml . Doctors use a scale called the amniotic fluid index (AFI) to check healthy levels of amniotic fluid. AFI measurements are in centimeters (cm). A typical AFI score is 5–25 cm .

What is amniotic fluid index (AFI)?

Amniotic fluid index (AFI) is the estimate of the volume of the fluid occupying the bag of waters that surround the unborn baby inside the uterus (called as the amniotic fluid) of a pregnant woman. This routinely used index of fetal well-being uses ultrasound to measure the amount of amniotic fluid. The normal range for the AFI is 5-18 cms.

What does AFI stand for in pregnancy?

The amniotic fluid index (AFI) is a test often performed weekly toward the end of pregnancy in women with high blood pressure, diabetes or other medical problems.

  • An AFI between 8-18 is considered normal.
  • An AFI < 5-6 is considered as oligohydramnios.
  • An AFI > 24-25 is considered as polyhydramnios.
