Chromosome Analysis and Fluorescence In Situ Hybridization (FISH) performed on amniotic fluid or chorionic villi samples, and Microarray Analysis performed on amniotic/fetal fluid or chorionic villi samples, can provide diagnostic information about a current pregnancy, including whether or not the fetus has certain genetic abnormalities such as the presence or absence of chromosomal regions (Down syndrome or Trisomy) and submicroscopic copy number changes associated with other genetic conditions.
Pregnancy Loss testing
Chromosome Analysis and Microarray Analysis performed on fetal tissue or products of conception from a pregnancy loss can often identify an underlying genetic cause. At least 10-15% of all recognized pregnancies are miscarried. Chromosome abnormalities cause more than 50% of first trimester losses and 15% of second trimester losses.1 In most instances, identification of a chromosomal cause for pregnancy loss allows calculation of accurate recurrence risks; families and providers use risks to determine appropriate fertility and pregnancy management.

Male Infertility testing
Chromosome Analysis and Y Chromosome Microdeletion (YCMD) Analysis can be performed on blood from a male to determine a possible explanation for infertility. While our laboratory classifies these tests as 'postnatal', they can be ordered through both our Prenatal and Postnatal test menus.
Genetic counseling services
In the increasingly complex field of genetic diagnostic testing, genetic counselors serve as a vital link between the laboratory and the clinician. As part of our comprehensive services, the Human Genetics Laboratory team includes licensed and board-certified genetic counselors to assist providers and their patients. Our genetic counselors have current clinical experience as well as dedicated areas of expertise, ranging from prenatal and postnatal genetics to oncology.
