A Limited Study for Amniotic Fluid Index (AFI) and Doppler is a specialized ultrasound performed to assess the amount of amniotic fluid around the baby
What is a Limited Study for AFI & Doppler?
It’s an ultrasound done to check two things – the amniotic fluid level and blood flow.
When is it Done?
This scan is usually done after 27 weeks of pregnancy if the doctor has concerns. They want to check the amount of amniotic fluid around the baby and how well blood is flowing to the baby. It helps monitor the baby’s health and growth in the later months.
Why do they check the amniotic fluid levels?
They want to make sure the amount of fluid surrounding the baby is in a healthy range. The fluid protects the baby and helps with growth.
Why do they use Doppler ultrasound?
Doppler helps them check the blood flow in important vessels like the umbilical cord. This lets them know the baby is getting enough blood and nutrients from the placenta.
Why do they monitor the baby’s growth?
They track the baby’s size and development over time. This helps ensure the baby is growing properly in the womb.
Why do they check the placenta and cord?
The placenta and cord provide food and oxygen from mom to baby. Checking for issues helps protect the baby’s health.
Why do they assess the baby’s overall health?
The ultrasounds give doctors a full picture of how baby is doing in there. This helps them know baby is safe and developing with no concerning problems.
How is an amniotic fluid index scan done?
The scan is done by placing a transducer on your belly after applying gel. The sonographer captures images and measures the amniotic fluid and baby’s blood flow.
Drink water before to fill your bladder for clearer images. Wear comfortable, loose clothing.
The scan takes 15-30 minutes. Images and measurements assess amniotic fluid levels and blood flow to your baby.
After, you can discuss the results with your doctor. They’ll explain what the findings mean for your pregnancy. Book your next scan to keep monitoring your pregnancy.
Reports are ready in 10-15 minutes.

A normal Amniotic Fluid Index (AFI) usually ranges between 8 to 18 cm. Values lower or higher than this may require closer monitoring by your doctor.
Yes, AFI and Doppler scans are completely safe and non-invasive. They use ultrasound waves and do not involve radiation.
Doppler scans help assess blood flow from the placenta to the baby, ensuring the baby receives enough oxygen and nutrients, especially in late pregnancy.
The frequency depends on your doctor’s advice. In high-risk pregnancies, it may be done weekly or biweekly after 28 weeks.
Low AFI (oligohydramnios) may indicate reduced fluid around the baby. Your doctor may advise more frequent scans, hydration, medication, or early delivery if needed.
An abnormal Doppler result may suggest reduced blood flow to the baby. This helps doctors plan timely care to protect the baby’s health.
No fasting is required. You may be advised to drink water before the scan for better imaging.
