%X ABSTRACT: Aneuploidies are one of the important causes of perinatal morbidity and mortality. Initially screening for aneuploidies started with maternal age risk estimation. Later on, serum testing for biochemical markers and ultrasound markers were added. Women detected to be at high risk for aneuploidies were offered invasive testing. Recently, various methods including non-invasive prenatal testing (NIPT) by analysis of cell-free fetal DNA (cffDNA) in maternal blood has shown promise for highly accurate detection of common fetal autosomal trisomies. Incorporating these new non-invasive technologies into clinical practice will impact the current prenatal screening paradigm for fetal aneuploidy, in which genetic counselling plays an integral role. The advantage of the technique being elimination of risks such as miscarriage associated with invasive diagnostic procedures. But then this new technique has its own set of technical limitations and ethical issues at present and further research is required before implementation. Data was obtained through a literature search via Pubmed and Google as well as detailed search of our library database.
