Chromosomal Microarray versus Karotyping for Prenatal Diagnosis

By on October 23, 2015

When performing chorionic villous sampling (CVS) or amniocentesis, the traditional laboratory analysis performed is a karyotype, which essentially views and counts the 46 chromosomes to diagnose conditions such as Down Syndrome, Trisomy 18, Trisomy 13, as well as establish the fetal gender. As co-investigators in this landmark 2012 publication in the New England Journal of Medicine and co-authors of this study, we were able to help establish non-invasive microarray testing as a reliable alternative to traditional invasive karyotype analysis.
