What is a genetic counselor?
Genetic counselors are master’s degree-trained heath care providers, who are experts in the field of genetics. The genetic counselors in the Division of Clinical Genetics are licensed by the State of Illinois and are board certified/eligible by the American Board of Genetic Counseling (ABGC). The role of the genetic counselor is to help you understand various genetic conditions and the risk of them occurring in a current or future pregnancy.  Our genetic counselors specialize in reproductive genetics and will answer all of your questions about fetal risk for birth defects, chromosome abnormalities and genetic conditions, as well as current screening and diagnostic testing options. Genetic counselors are specifically trained to explain risks and test results in understandable terms and to help you make informed family planning and pregnancy management decisions. Our genetic counselors excel in providing the highest quality genetic counseling available.
