In brief: Yes

The diagnostic test for down syndrome is a fetal chromosome analysis or karyotype with fetal cells obtained by either chorionic villus sampling or amniocentesis.
Both tests have complication risks. There are less invasive tests using ultrasound and blood tests that can suggest an elevated risk, but they only assess risks and are not diagnostic.
