We test babies born in Washington State for the treatable disorders listed below. Babies with these conditions usually appear normal at birth. Without screening, babies with these disorders are not likely to be detected before disability or death occurs. Our testing and follow-up services allow early diagnosis and treatment.
This screening is mandated by statute (Chapter 70.83 RCW) with regulations adopted by the State Board of Health (Chapter 246-650 WAC).
Although not mandated, a routine second newborn screen is recommended for all infants between 7 and 14 days of age as a standard of medical practice to optimize disease detection for all infants.
