AFI is measured after which gestational week?

Explanation:
Amniotic fluid index is an ultrasound method to estimate amniotic fluid volume by measuring the deepest pockets in four uterine quadrants and adding them together. This technique requires enough fluid and a uterus large enough to visualize and quantify those pockets reliably. Before about 20 weeks, both the fluid volume and the uterine size are often too small for four distinct pockets to be measured accurately, making the AFI measurement unreliable. Once around 20 weeks gestation, the fluid volume is typically sufficient and the measurement becomes practical and meaningful. In practice, AFI is used primarily in the second and third trimesters to monitor for oligohydramnios or polyhydramnios, with 20 weeks marking the earliest reliable point for this assessment.
