Tennessee has a comprehensive genetics program that provides access to genetic screening, diagnostic testing and counseling services for individuals and families who have, or are at risk for, genetic disorders. Two major aspects of the genetics program are

• Newborn Screening (NBS) for genetic/metabolic disorders; and
• Newborn Hearing Screening (NHS) for early detection of hearing loss.

These comprehensive screening programs are set up as a public health service for the citizens of Tennessee.

NBS allows for early diagnosis of metabolic disorders followed by appropriate medical treatment. Early diagnosis and treatment can make the difference between a child leading a relatively normal life or having more significant developmental delays, long-term healthcare needs or even death.

NHS allows for early diagnosis of hearing loss and appropriate follow up services. Early detection gives parents the most effect opportunity to take action to help prevent the complications of inability to communicate, trouble reading, difficulty learning and isolation.
