At what stage is chorionic villus sampling done?

10-12 weeks: Chorionic villus sampling (cvs) obtains cells from the fetoplacenta for testing at 10-12 weeks of pregnancy, amniocentesis obtains fetal skin/urine cells at 16-18 weeks. Higher risks for miscarriage (2-3% for cvs, <0.5% or negligible for amnio) balance against the cvs advantage of testing before a women "shows, " preserving the privacy of pregnancy (testing).

About 8 weeks: Keep in mind that this is the first trimester and risk of pregnancy loss in increased when compared to amniocentesis, which is usually done in the second trimester for diagnostic purposes.
