The article discusses the implications of the chromosomal microarray analysis, a noninvasive test of fetal DNA that allows doctors to detect submicroscopic genetic abnormalities. It is said that advocates of this technological test say that it is safer, faster and more accurate than invasive diagnostic procedures such as amniocentesis. However, some people worry that the tests will result in prenatal genetic information of uncertain significance, which may cause confusion and anxiety for expectant parents. The article discusses such issues as identifying genetic problems, providing genetic counselling to parents, and the ethical concerns of the testing.
