Trisomy 21 abnormalities can be detected in the womb by a noninvasive technique which is less risky than amniocenteses, finds a new study. Amniocenteses has been associated with miscarriages in previous studies.
NIPT Detects More Than 80 Percent of Chromosomal Abnormalities: Study
Researchers will report that noninvasive prenatal testing detected 83.2 percent of chromosomal abnormalities normally picked up by invasive diagnostic testing strategies, such as chorionic villus sampling (CVS) or amniocentesis.

If pregnant women at an increased risk of fetal trisomy 21 were offered an NIPD, some of the miscarriages caused by invasive testing could probably be prevented.
No robust estimations of the sensitivity and specificity of the tests on the rare trisomies 13 and 18 are possible. With over 99 percent for trisomy 21, sensitivity and specificity of the tests are similar to those of invasive methods.

Simple Foetal Blood Test Soon To Predict Chromosomal Abnormalities
Researchers in The Netherlands are on the verge of developing a simple, prenatal blood test that would be able to detect accurately chromosomal abnormalities in the developing foetus.

Researchers Find New Clue to Causes of Birth Defects
Researchers have found a possible clue to why older mothers face a higher risk for having babies born with conditions such as Down syndrome that are characterized by abnormal chromosome numbers.

Empowered Prenatal Diagnostic Environment In Which DNA Sequencing Becomes The Standard Of Care
Scientists reported that the whole genome sequencing of the DNA code of three prenatal samples provided a detailed map of the locations of their chromosomal abnormalities in 14 days.
