What is Non-Invasive Prenatal Testing?
NIPT testing is a form of noninvasive prenatal genetic testing screening which determines the risk of a fetus being born with specific genetic conditions. The blood of a pregnant woman contains very small fragments of her unborn baby’s DNA, which due to their free-floating nature are known as cell-free DNA (cfDNA). These cells are shed from the placenta during the course of a pregnancy and are, for the most part, identical to the DNA of the fetus. This allows for a genetic screening method that can detect with a high degree of accuracy specific genetic changes or mutations which might put the fetus at higher risk for developing certain genetic conditions.
