Alpha Fetoprotein, Amniotic Fluid

What is the AF from Amniotic Fluid test?

This refers to various laboratory evaluations performed on amniotic fluid (AF) collected during amniocentesis, including genetic tests, infection markers, and lung maturity assessments.


Why is this test done?

It provides valuable information in prenatal care, especially for high-risk pregnancies, helping diagnose chromosomal abnormalities (like Down syndrome), fetal infections, or assess the maturity of the fetal lungs.


How is the test performed?

Under ultrasound guidance, a thin needle is inserted into the uterus to withdraw a small amount of amniotic fluid, which is then sent to the lab for analysis.


What do the results mean?

Results vary depending on the tests requested. Genetic findings may suggest inherited disorders, while biochemical tests can determine fetal organ development.


Are there any precautions or preparations required?

The test should be performed in a specialized clinical setting. Post-procedure rest is sometimes advised.
