https://phgkb.cdc.gov/PHGKB/specificPHGKB.action?topic=rare&query=home From the abstract: "Newborn bloodspot screening (NBS) began in the early 1960s based on the work of Dr. Robert “Bob” Guthrie in Buffalo, NY, USA. His development of a screening test for phenylketonuria on blood absorbed onto a special filter paper and transported to a remote testing laboratory began it all. Expansion of NBS to large numbers of asymptomatic congenital conditions flourishes in many settings while it has not yet been realized in others. "
