Quizplus · Accepted Answer

Noninvasive prenatal testing (NIPT) is a procedure that analyses small fragments of fetal DNA that are present in the mother's bloodstream. This test can screen for chromosomal abnormalities such as Down syndrome, without the need for invasive procedures like chorionic villus sampling. Preimplantation genetic diagnosis (PGD) is a technique used during in vitro fertilization, where a single cell from a developing embryo is biopsied and tested for genetic abnormalities before implantation. Aneuploidy refers to an abnormal number of chromosomes in a cell or embryo. Chorionic villus sampling is an invasive prenatal testing method where a sample of the placenta is taken for genetic analysis.
