What is the normal range for the amniotic fluid index (AFI)?

The normal range for the amniotic fluid index (AFI) is indeed 5-25 cm. This measurement is crucial in assessing fetal well-being and the adequacy of amniotic fluid, which plays a significant role in fetal development and movement. An AFI within this range indicates a healthy amount of amniotic fluid, suggesting that the fetus is likely receiving adequate nutrients and space for growth, and there are no immediate concerns regarding oligohydramnios (low fluid) or polyhydramnios (high fluid).

An AFI lower than 5 suggests oligohydramnios, which can indicate issues such as placental insufficiency or fetal renal problems. Conversely, an AFI above 25 indicates polyhydramnios, which can be associated with diabetic mothers or fetal anomalies. Monitoring the AFI is an essential part of prenatal care, helping to inform clinical decisions regarding the timing of delivery or further investigations. This reinforces the significance of the chosen answer, as it reflects a healthy state of amniotic fluid, crucial for both the mother and developing fetus.
