If an AFI shows a fluid level of fewer than 5 centimeters (or less than the 5th percentile), the absence of a fluid pocket 2-3 cm in-depth, or a fluid volume of less than 500mL at 32-36 weeks gestation, then a diagnosis of oligohydramnios would be suspected.Necessary cookies are absolutely essential for the website to function properly.

If a woman is past her due date by two weeks or more, she may be at risk for low amniotic fluid levels since fluids can decrease by half once she reaches 42 weeks gestation.

The four values of the AF were summed to get the AFI. More subjective approach than amniotic fluid assessment.

Normal AFI values range from 5 to 25 cm [1, 4]. Measurement of the head circumference, biparietal diameter, abdominal circumference, and femoral length of the fetus were obtained.
