Afi Pregnancy Test. It is part of the fetal biophysical profile. The amniotic fluid index afi is an estimate of the amniotic fluid volume in a pregnant uterus. It cushions your baby helps the development of your baby s lungs digestive system and muscle development and helps protect the umbilical cord from too much compression. Afi is the sum of the deepest vertical pocket of fluid excluding fetal parts and umbilical cord in four quadrants between the maternal midline vertically and a transverse line halfway between the pubic symphysis and uterine fundus 14 27 sdp is a measure of the single deepest pocket of fluid.
Technique the uterus is divided into four imaginary quadrants with the linea nigra and a mediolateral. It estimates the amount of amniotic fluid in the fetal sac to make sure there isn t too much a condition called polyhydramnios or too little a condition called oligohydramnios. To determine the afi doctors may use a four quadrant technique 2 when the deepest unobstructed vertical length of each pocket of fluid is measured in each quadrant and then added up to the others 3 or the so called single deepest pocket technique.
