In addition, a pregnant woman carrying a child with Edwards' syndrome may have an unusually large uterus during pregnancy, due to the presence of extra amniotic fluid (polyhydramnios).
The level of AFP can also be determined by analyzing a sample of amniotic fluid.
By analyzing the amount of AFP found in a blood or amniotic fluid sample, doctors can determine the probability that the fetus is at risk for certain birth defects.
If the tube that becomes the brain and spinal cord does not close correctly during fetal development, AFP may leak through this abnormal opening and enter the amniotic fluid.
This leakage creates abnormally high levels of AFP in amniotic fluid and in maternal blood.
For a fetus, AFP can also be measured in the sample of amniotic fluid taken at the time of amniocentesis.
This can be indicated by the FHR pattern, amniotic fluid status, and fetal movement patterns.
The MBPP is performed in the same manner as the NST with a limited ultrasound (US) performed to assess the amount of amniotic fluid, which is reported as the amniotic fluid index (AFI).
Following the NST, an US is done to observe the amount of amniotic fluid present in four quadrants, which are divided along the umbilicus midline and perpendicular to the midline.
The ultrasonographer/examiner looks for gross fetal movement, i.e., kicking and moving around; fetal tone, i.e., making a fist; breathing movements (which the mother can often perceive as hiccoughs); and amniotic fluid volume.
For the amniocentesis, an US is used to determine an appropriate place to insert a needle and withdraw amniotic fluid for testing.
If premature birth is expected, or there is some condition that calls for delivery as soon as possible, the amount of surfactant in the amniotic fluid will indicate how well the lungs have matured.
If little surfactant is found in an amniotic fluid sample taken by placing a needle in the uterus (amniocentesis), there is a definite risk of RDS.

Fluids - drinking at least 8 glasses of water, milk, 100 percent fruit or vegetable juices each day is necessary to maintain the right amount of amniotic fluid around your baby.
The procedure involves a long slim needle being passed through the abdomen of the pregnant woman to the uterus where amniotic fluid is carefully drawn from the amniotic sac.
There also can be slight leakage of amniotic fluid or minimal blood loss, but providing that the woman rests for a few hours afterwards and avoids strenuous activity for 24 hours afterwards, this can be kept to a minimum.
There are rare occasions when there may be problems performing the test and these situations usually involve an inability to obtain the necessary amniotic fluid.
No. The baby is safely enclosed in your amniotic sac.
Once the baby's location is determined, a long, thin needle is inserted into the abdomen and fluid from the amniotic sac is withdrawn.
An amnio is performed by a trained physician who inserts a long needle in the abdomen and draws out some of the amniotic fluid that fills the sac.
The needle extracts a small amount of amniotic fluid out of the sac surrounding the baby.
After your test is performed, the amniotic fluid is sent to a lab.
From the amniotic fluid, lab technicians can determine the sex of the baby as well as other chromosomal abnormalities that indicate a genetic defect.

The water in the amniotic sac is a protective substance that protects the baby from infection and it acts as a cushion to protect the baby from injury.
The fluid-filled amniotic sac surrounding your baby will rupture before delivery.
Once the amniotic sac has ruptured, there is a risk of infection if bacteria is introduced into the vagina.
The amniotic sac is a protective barrier for the baby and delivery should occur shortly after the water breaks.
