Prenatal testing is used to detect changes in a fetus' genes or chromosomes when performed on amniotic fluid or CVS from a current pregnancy. Pregnancy loss testing is used to detect changes in a fetus' genes or chromosomes after a pregnancy loss when performed on products of conception or fetal tissue.
Postnatal testing for newborns, adolescents, and adults is used to diagnose or rule out a genetic or chromosomal condition. In many cases, postnatal testing looks to confirm a diagnosis when a particular condition is suspected based on physical mutations and symptoms.
Genetic testing can identify inherited gene mutations that might increase a person’s risk of developing cancer, or confirm a suspected gene mutation in a person or family.
Performed on blood, bone marrow, lymph node, or solid tumor tissue, genetic testing can detect chromosome aberrations associated with hematology and oncology conditions. Often times, individual chromosomes are further analyzed after a cancer diagnosis to provide prognostic information to assist in disease management.
