Most genetic counseling sessions take under an hour. Your genetic counselor will discuss with you the risks, benefits and limitations of genetic testing, as well as the overall implication to a pregnancy.

We want to give you and your partner all the information we can to assist you in thinking through the many options routinely offered to patients before and during pregnancy.
