Laboratory testing: Cvs sampling after 10 weeks of gestation can obtain tissue for testing. The tests usually done are chromosomal analysis or mutational analysis of a specific gene.

Question 4

Accepted Answer

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).
