Chorionic villus sampling test is used to determine the genetic disorder or chromosomal disorder in a fetus. Chorionic villus test is done by the PCR or by FISH. This test can take place usually performed in 10 to 12 weeks gestation i.e. first trimester, before amniocentesis. Chorionic villus can be removed by a needle.
