Normal AFI range?

Normal AFI range?

• A. 6-14
• B. 8-18
• C. 10-20
• D. 5-12

Answer: (B)

Amniotic Fluid Index (AFI) sums the amniotic fluid in four ultrasound quadrants to estimate the total fetal amniotic fluid volume. A normal AFI is about 8 to 18 centimeters. Values below 8 cm indicate oligohydramnios, which can be linked to issues like placental insufficiency, post-term pregnancy, ruptured membranes, or fetal renal problems. Values above 18 cm indicate polyhydramnios, which can occur with maternal diabetes, fetal GI obstructions, or certain fetal anomalies. Knowing this range helps you interpret ultrasound findings and guide care, so 8–18 cm is considered the normal range.
