What is an Amniotic Fluid Index (AFI) Scan?
The Amniotic Fluid Index (AFI) scan is a key ultrasound test that measures the amount of amniotic fluid surrounding the baby inside the uterus. This fluid is essential for the baby’s growth, movement, and lung development and acts as a cushion to protect the baby.
Why is This Scan Important?
The amount of amniotic fluid offers crucial insights into how well the placenta and baby are functioning. Too little or too much fluid can indicate possible complications. The AFI scan helps:
- Detect low (oligohydramnios) or high (polyhydramnios) fluid levels
- Monitor placental function
- Assess baby’s urine output and overall health
- Guide decisions on delivery timing if needed
Who Needs an AFI Scan?
- Mothers with gestational diabetes, hypertension, or pre-eclampsia
- In cases of reduced fetal movements
- If there’s a concern about intrauterine growth restriction (IUGR)
- Women with a history of fluid abnormalities in previous pregnancies
- During routine growth scans in the third trimester
When is the AFI Scan Performed?
- Typically done during the third trimester
- Often repeated in high-risk pregnancies or in the final weeks before delivery
- Can be included as part of the Growth Scan or Biophysical Profile (BPP)
How is the Scan Done?
- Conducted via abdominal ultrasound
- The uterus is divided into four quadrants
- The depth of amniotic fluid in each quadrant is measured and totaled
- The scan is safe, painless, and takes around 10–15 minutes
What is a Normal AFI Range?
- 8 to 18 cm is generally considered normal
- Below 5 cm may indicate low fluid (oligohydramnios)
- Above 24 cm may suggest excess fluid (polyhydramnios)
These values help doctors plan follow-up care or interventions if needed.
