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).

Risk: Risk of pregnancy loss with cvs and amniocentesis are equivalent. That's been shown by four different studies. In experienced hands the loss rate is something like 1 in 1600.
