Chronic villus sampling
WebWhat the chorionic villus samplers? Chorionic villus testing (CVS), or chorionic villus biopsy, is a premature examine that imply taking adenine sample of tissue from an placenta to test for chromosomal abnormalities and certain other genetic problems. WebConsidered noninvasive, this test is safe and reliable, and may avoid alternative genetic testing by amniocentesis or chorionic villus sampling, which risks causing spontaneous abortion. Ethical and legal issues of cffDNA testing will become more acute if testing expands to fetal whole-genome sequencing.
