Cell-free Fetal Nucleic Acid Identifier Markers in Maternal Circulation
From the discovery of cell-free fetal (cff)-DNA in 1997 so far, many studies have been performed on various aspects of cff-nucleic acid. It is undoubted that currently, invasive prenatal diagnosis progresses to the noninvasive test. However, there are many problems. One of the most challenging issues in this field is differentiation and detection of the small amount of cff-nucleic acid in mater...
متن کاملComparison of noninvasive prenatal testing of cell‐free DNA in maternal blood and amniocentesis for evaluation of aneuploidy
Background: The aim of this study was to compare noninvasive prenatal testing (NIPT) of cell‐free DNA in maternal blood and amniocentesis in the diagnosis of aneuploidy. This study was designed to evaluate sensitivity, specificity, accuracy, positive predictive value and negative predictive value of NIPT for detection of aneuploidies compared gold standard test of amniocentesis. Materials and m...
متن کاملCell-free fetal DNA in the maternal circulation and its future uses in obstetrics.
OBJECTIVE To provide an introduction to new technologies involving maternal plasma cell-free fetal DNA for non-invasive prenatal diagnosis and screening in obstetrics. OPTIONS Limited to introductory discussion of maternal plasma cell-free fetal DNA. EVIDENCE MEDLINE was searched to identify publications related to the topic after 1996. This document represents an abstraction of the informa...
متن کاملNon-invasive prenatal testing using cell-free fetal DNA in maternal circulation.
The identification of cell-free fetal DNA (cffDNA) in maternal circulation has made non-invasive prenatal testing (NIPT) possible. Maternal plasma cell free DNA is a mixture of maternal and fetal DNA, of which, fetal DNA represents a minor population in maternal plasma. Therefore, methods with high sensitivity and precision are required to detect and differentiate fetal DNA from the large backg...
متن کاملTracking embryo implantation using cell-free fetal DNA enriched from maternal circulation at 9 weeks gestation.
Embryo DNA fingerprinting represents an important tool for tracking embryo-specific outcomes after multiple embryo transfer during IVF. The situation in which two embryos are transferred and only one implants represents a unique opportunity for the most well-controlled validation of markers capable of identifying competent and incompetent embryos. Specifically, this design eliminates all patien...
