Up to a third of babies admitted to the NICU have a genetic disorder.1 Proper treatment and management depend on accurate diagnosis, and DNA testing can help. Our flexible testing options are available to aid in timely diagnostic assessment and confirmation.

Below is a list of our testing most relevant to patients in the NICU, with links for more details.
