Non-Invasive Prenatal Diagnosis in Twin Pregnancies: Current Status
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...
متن کاملInvasive or non-invasive prenatal genetic diagnosis?
About 40 years ago, invasive prenatal diagnosis techniques were introduced in obstetrics. Initially, amniocentesis was performed followed by placentacentesis, fetoscopy, fetal blood sampling (FBS), and chorionic villus sampling (CVS). These procedures, while invading the uterine environment, have made it possible to proceed with the retrieval of biological tissue of fetal origin for analysis an...
متن کاملRapid and Non Invasive Prenatal Diagnosis
Prenatal screening and diagnosis are routinely offered at antenatal care clinic visits, and are important in decision making about the continuation of pregnancies affected by genetic conditions for which there are no cures, and prevention through therapeutic abortion is a reasonable option. Prenatal screening is offered to all pregnant women and include fetal ultrasonography and maternal serum ...
متن کاملNon-Invasive Prenatal Diagnosis in the Management of Preimplantation Genetic Diagnosis Pregnancies
Prenatal diagnosis (PD) is recommended in pregnancies after a Preimplantation Genetic Diagnosis (PGD). However, conventional PD entails a risk of fetal loss which makes PGD patients reluctant to undergo obstetric invasive procedures. The presence of circulating fetal DNA in maternal blood allows performing a non-invasive prenatal diagnosis (NIPD) without risk for the pregnancy outcome. This wor...
متن کاملI-40: Non Invasive Prenatal Genetic Diagnosis;Current Status and The Future
Discovery of cell free fetal DNA in 1997 has deeply changed the outlook of prenatal diagnosis approaches as most of the clinically established screening tests are not sensitive/specific enough while the current practical diagnostic tests are also invasive in their nature. The most common prenatal screening test is routinely practiced for the diagnosis of Down syndrome (DS) which includes a 10% ...
