Prenatal testing in recent years has been moving toward non-invasive methods to determine the fetal risk for genetic disorders without incurring the risk of miscarriage Rapid progress of modern high-throughput molecular technologies along with the discovery of cell-free fetal DNA in

Noninvasive prenatal screening for fetal common

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

We recently demonstrated noninvasive detection of fetal aneuploidy by shotgun sequencing cell-free DNA in maternal plasma using next-generation high throughput sequencer However GC bias introduced by the sequencer placed a practical limit on the sensitivity of aneuploidy detection In this study we describe a method to computationally remove GC bias in short read sequencing data by

Non-invasive prenatal testing is a blood test for identifying chromosomal abnormalities in high-risk pregnancies The test is as simple as a blood draw and helps identify any genetic abnormalities in an unborn baby The NIPT Test: As Simple As It Can Get NIPT test is similar to any other routine blood test The pregnant woman's blood sample is collected using a simple needle and syringe The

Rh factor testing

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

Knowledge and Attitudes Regarding Non

Prenatal testing is an expansive field and methods have im-proved dramatically in the past few years The most recently implemented method is non-invasive prenatal testing (NIPT) for analysis of fetal aneuploidy In a blood sample from the pregnant woman circulating fetal cell free DNA (cfDNA) is present and can be used for analysis (Lo et al

Genomics-based non-invasive prenatal testing methods appear to be sensitive and highly specific for detection of fetal trisomies 21 18 and 13 in high-risk populations There is paucity of data on the accuracy of gNIPT as a first-tier aneuploidy screening test in a population of unselected pregnant women With respect to the replacement of invasive tests the performance of gNIPT observed in

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


14 02 2019BACKGROUND: High-throughput non-invasive prenatal testing (NIPT) for fetal Rhesus D (RhD) status could avoid unnecessary treatment with anti-D immunoglobulin for RhD-negative women found to be carrying an RhD-negative fetus We aimed to assess the diagnostic accuracy of high-throughput NIPT for fetal RhD status in RhD-negative women not known to be sensitized to the RhD
