PRENATAL DEVELOPMENT 2 Prenatal Development: Non-invasive Prenatal Testing Non-invasive prenatal testing (NIPT) or non-invasive prenatal diagnosis (NIPD) can detect specific types of chromosomal abnormalities in a fetus. NIPT is a newer screening method that is able to help determine if there is risk for Turner syndrome, Edwards syndrome, Patau syndrome, as well as Down syndrome ( Non-invasive , 2016). NIPT is a blood test that looks at the fetal DNA within the maternal bloodstream. NIPT is also used to determine the sex of the fetus and the blood type. More common methods used to detect chromosomal abnormalities are invasive prenatal genetic tests such as chorionic villus sampling (CVS) and amniocentesis. These methods involve a risk of miscarriage and are why NIPT is often substituted in its place ( Non- invasive , 2016). There is a high demand for non-invasive prenatal testing from gynecologists and expectant mothers. Also, the increasing rate at which Down syndrome is being detected is propelling the need and demand for NIPT ( Non-invasive , 2016). NIPT has been positively impacted by the advanced age of expectant mothers who want to have a child with no risk of miscarriage. The growth of the NIPT market might be slightly halted in the years to come due to other more advanced screening methods and regulatory guidelines ( Non-invasive , 2016). According to Morris, Karlsen, Chung, Hill, and Chitty (2014) the National Screening Committee (NSC) determines the screening standards in the UK for antenatal screening and puts out a widespread recommendation that all women should be offered a Down syndrome screening. The DS screening is typically performed between 11 and 14 weeks gestation. Morris et al. reported that the National Health Service (NHS) has an 85% detection rate and a screen positive rate of 2.5% (meaning that the NHS can be considered very reliable in DS screenings). The benefit of a DS screening is to determine if a baby has Down syndrome or not. If a woman

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
