In brief: Amnio or CVS

Typically the term "invasive prenatal diagnosis" applies to two tests commonly performed to obtain fetal genetic information, amniocentesis and chorionic villus sampling.
The word "invasive" is used for procedures like these because the uterus is entered through a needle into amniotic sac or through a catheter into placental tissue, respectively.

In brief: Genetic testing

Prenatal diagnostic testing usually involves obtaining fetal tissue from the uterus.
That is typically done early (about 9 to 11 weeks) in a pregnancy by chorionic villus sampling and later (15 weeks or later) by amniocentesis.
