Fetal sex determination using circulating cell-free fetal DNA (ccffDNA) at 11 to 13 weeks of gestation.
OBJECTIVE To examine the performance of a mass spectrometry-based detection platform using three Y-chromosome sequences for fetal sex determination from circulating cell-free fetal DNA (ccffDNA) in maternal blood in the first trimester of pregnancy. METHODS We extracted ccffDNA for the determination of fetal sex from stored maternal plasma obtained at 11 to 13 weeks' gestation from singleton ...

in previous years, identification of fetal cells in maternal blood circulation has caused a new revolution in non-invasive method of prenatal diagnosis. low number of fetal cells in maternal blood and long-term survival after pregnancy limited the use of fetal cells in diagnostic and clinical applications. with the discovery of cell-free fetal dna (cffdna) in plasma of pregnant women, access to...
متن کاملearly fetal gender determination using real-time pcr analysis of cell-free fetal dna during 6th-10th weeks of gestation.
nowadays, new advances in the use of cell free fetal dna (cffdna) in maternal plasma of pregnant women has provided the possibility of applying cffdna in prenatal diagnosis as a non-invasive method. in contrary to the risks of invasive methods that affect both mother and fetus, applying cffdna is proven to be highly effective with lower risk. one of the applications of prenatal diagnosis is fet...
