Exploring The Different Types Of NIPT Tests
Non-Invasive Prenatal Testing (NIPT) is a screening method that analyzes fetal DNA in maternal blood to detect chromosomal abnormalities. NIPT has evolved significantly since its inception in 1997 and now offers several types of tests with varying degrees of accuracy and cost-effectiveness.
Cell-Free DNA Testing Cell-free DNA (cfDNA) testing is the most common type of NIPT and analyzes the DNA fragments that circulate freely in the maternal bloodstream. This test is highly accurate for detecting Down syndrome and other trisomies, but is less effective for detecting sex chromosome abnormalities and microdeletions.
Whole Genome Sequencing Whole genome sequencing (WGS) is a type of NIPT that analyzes the entire genome of the fetus. This test is highly accurate for detecting chromosomal abnormalities and can also detect genetic mutations that cause inherited disorders. However, WGS is currently the most expensive type of NIPT.
Targeted Sequencing Targeted sequencing is a type of NIPT that analyzes specific regions of the fetal genome that are known to be associated with chromosomal abnormalities. This test is less expensive than WGS and more accurate than cfDNA testing for detecting sex chromosome abnormalities and microdeletions.
Placental DNA Testing Placental DNA testing is a type of NIPT that analyzes DNA from the placenta, which is obtained through chorionic villus sampling (CVS) or amniocentesis. This test is highly accurate for detecting chromosomal abnormalities and can also detect genetic mutations. However, it carries a small risk of miscarriage.
Conclusion NIPT has revolutionized prenatal screening and offers several types of tests with varying degrees of accuracy and cost-effectiveness. The choice of which test to use depends on the specific needs and preferences of each patient. As technology continues to advance, it is likely that NIPT will become even more accurate and accessible in the future.
