Currently Washington screens for ten disorders: biotinidase deficiency, congenital adrenal hyperplasia (CAH), congenital hypothyroidism (CH),  cystic fibrosis (CF), galactosemia, hemoglobinopathies (HB), homocystinuria, Maple Syrup Urine Disease (MSUD),  Medium Chain Acyl co-A Dehydrogenase Deficiency (MCADD) and phenylketonuria (PKU). 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.
