Amniocentesis is a medical procedure used in prenatal diagnosis of chromosomal abnormalities and fetal infections, and also for sex determination, in which a small amount of amniotic fluid, which contains fetal tissues, is sampled from the amniotic sac surrounding a developing fetus, and then the fetal DNA is examined for genetic abnormalities. The most common reason to have an amnio is to determine whether a baby has certain genetic disorders or a chromosomal abnormality, such as Down syndrom
Amniocentesis is invasive, carries risks, and canât be done until the 15th to 20th week of pregnancy. Now there is a safe, noninvasive, accurate blood test that can be done as early as the 9th week. It analyzes cell-free fetal DNA (cfDNA) circulating in the motherâs blood. It sounds ideal, but there are some caveats. Itâs not yet appropriate to recommend it to all pregnant women.
