Genetic Testing and Counseling in the NICU.

Abstract

Advances in prenatal and postnatal genetic testing have greatly improved the identification and management of genetic and chromosomal conditions in neonates. By understanding the benefits and limitations of genetic testing, health care providers can ensure that patients receive comprehensive, evidence-based support when navigating complex reproductive decisions. We begin with a review of fundamental embryologic development and genetic principles, emphasizing the need for informed consent and patient education in genetic screening. Variations in genetic makeup, including chromosomal abnormalities and their implications for reproductive health, are explored. Next, the article explores the evolution of testing methodologies, the importance of genetic counseling, and the role of interdisciplinary health care teams in supporting patients. While genetic counselors provide specialized expertise, nurses can play a crucial role in bridging gaps in access to genetic information.
