In brief: Yes
The test by sequenom is a blood test from the mother as early as 10 weeks used to analyze circulating fetal blood cells for their chromosomal structure.
This can help determine if the fetus suffers from a number of chromosomal abnormalities including down's syndrome. It can also determine the sex but in the case of female fetuses it is more problematic because of cross contamination.
