What is considered low amniotic fluid at 37 weeks?
A normal measurement is 2 to 8 centimeters (cm). A finding of less than 2 cm indicates low amniotic fluid at this stage. After 24 weeks of pregnancy, the most common way to measure amniotic fluid is called the AFI, or amniotic fluid index.
What is the correct amount of amniotic fluid?
The amount of amniotic fluid is greatest at about 34 weeks (gestation) into the pregnancy, when it averages 800 mL. About 600 mL of amniotic fluid surrounds the baby at full term (40 weeks gestation). The amniotic fluid constantly moves (circulates) as the baby swallows and “inhales” the fluid, and then releases it.
