Detecting Chromosomal Abnormalities

In prenatal testing, a karyotype is the current “gold standard” test used to identify and evaluate the size, shape and number of chromosomes in a sample of fetal cells, most commonly obtained via amniocentesis or CVS.

The methods used in the genetic analysis of fetal cells are evolving in rapid and exciting ways. While the karyotype is still considered the gold standard for prenatal testing, other methods such as array comparative genomic hybridization (aCGH) and DNA sequencing are gaining acceptance due to the molecular nature of their results and the significant amount of detailed information these new approaches can reveal about the genetic makeup of the fetus.

Artemis Health’s approach of starting with a maternal blood sample and isolating intact fetal cells and DNA—and therefore the entire fetal genome—will allow us to take advantage of the most advanced and proven methods of genetic analysis, enabling us to provide the best possible information to women who use our tests.
