The field of prenatal genetic testing has exploded with new non-invasive technologies and test options in the past several years. It is challenging for women's healthcare providers to keep up with the multitude of publications and provide patients with the most accurate and up-to-date information possible regarding prenatal testing. In this article, we examine the sequencing technologies that p...

The objective of this review is to assess the evidence which supports the use of non-invasive prenatal diagnosis (NIPD) in twin pregnancies. Through the years, we have witnessed the technological developments in non-invasive prenatal diagnosis attained new heights, but those studies were usually limited in singleton pregnancies. As we known, twin pregnancies are at higher risk in both aneuploid...

Objective(s)—To determine how adults in the United States (US) view non-invasive prenatal testing using cell-free fetal DNA (cffDNA testing) in order to help estimate uptake. Study Design—A national sample of 1,861 US-based adults was surveyed using a validated online survey instrument. The survey was administered by a commercial survey research company. Respondents were randomized to receive a...

Current prenatal diagnosis uses non-invasive procedures of maternal serum screening and ultrasound exam to evaluate the risk of chromosomal abnormalities and invasive procedures of chorionic villus sampling and amniocentesis for the diagnosis of cytogenomic abnormalities and gene mutations. The discovery of cell free fetal DNA (cffDNA) in maternal blood prompted the application of massive paral...

Non-invasive prenatal testing has been in clinical use for a decade; however, there is evidence that this technology will be more widely applied within the next few years. Guidance is therefore required to ensure that the procedure is offered in a way that is evidence based and ethically and clinically acceptable. We conducted a systematic review of the current relevant literature to ascertain ...

context prenatal testing aims to identify fetal chromosomal and genetic disorders prior to delivery. current invasive procedures such as amniocentesis and chorionic villus sampling (cvs) pose a risk to mother and fetus and such diagnostic procedures are available only to high-risk pregnancies, which limits aneuploidy detection rate. the identification of cell-free fetal dna (cffdna) in maternal ...
