Objective To explore the feasibility of high-throughput massively parallel genomic DNA sequencing technology for the noninvasive prenatal detection of fetal chromosome aneuploidies (SCAs) Methods The study enrolled pregnant women who were prepared to undergo noninvasive prenatal testing (NIPT) in the second trimester Cell-free fetal DNA (cffDNA) was extracted from the mother's

Noninvasive prenatal diagnosis of hemophilia by

Current prenatal diagnosis for hemophilia largely relies on invasive procedures such as chorionic villus sampling which poses a finite risk to the fetuses 1 2 24 Consequently many pregnant women from at-risk families do not consent to invasive testing because of the associated risks 25 26 Noninvasive fetal determination by the use of circulating fetal DNA has provided one safe

Background Rhesus factor testing utilises the genotyping technique to detect the presence of the RhD gene By checking the existence of the RhD gene in the individual's genome the presence of rhesus D (RhD) antigens can be inferred Individuals with a positive RhD status has RhD antigens expressed on the cell membrane of their red blood cells whereas Rhesus D antigens are absent for

Committee Opinion No 545: Noninvasive prenatal testing

Noninvasive prenatal testing that uses cell free fetal DNA from the plasma of pregnant women offers tremendous potential as a screening tool for fetal aneuploidy Cell free fetal DNA testing should be an informed patient choice after pretest counseling and should not be part of routine prenatal laboratory assessment Cell free fetal DNA testing should not be offered to low-risk women or women

ABSTRACT Non-invasive prenatal testing (NIPT) is a new screen for fetal chromosomal abnormalities It is a screening test based on technology that involves the analysis of feto-placental DNA that is present in maternal blood This DNA is then analysed for abnormalities of specific chromosomes (eg 13 18 21 X Y) NIPT has a much higher screening capability for chromosomal abnormalities than
