Noninvasive prenatal DNA test

Noninvasive prenatal DNA Test (NIPT) or as popularly known as Noninvasive Prenatal Screening (NIPS) is a modus operandi regulating the probability of a fetus to born with an undeniable genetic abnormality. A small snippet of DNA is analyzed in this testing. The fragment of DNA should be collected from the blood circulating in women at the time of pregnancy. Unlike other DNA samples which are found in the nucleus of the cell, these snippets are found freely floating and not within the boundaries of cells therefore they are called cell-free DNA (cfDNA). This DNA snippet contains approximately two hundred DNA building blocks or sometimes even fewer. These cells come to light when cells die off or get broken down and their contents as well as the DNA are emancipated in the blood.

The procedure of the tests may or may not be dangerous. A woman who is carrying twins or triplets is not suggested a prenatal DNA test, if there is such a case a postnatal DNA test can be suggested by the doctor who is looking at the case.
