Newborn genomic screening in over 10,800 babies finds positive rates up to 3.7 percent
Four genomic newborn screening studies covering more than 10,800 babies in the US, Belgium, and Australia have published initial results, with screen-positive rates ranging from 1.6% to 3.7%. Stark and colleagues, writing in 2026, found that all four programs pulled DNA successfully from standard dried blood spots, a sign the approach can slot into existing screening infrastructure. G6PD deficiency turned up more than any other condition. But the studies used different panels and defined outcomes differently, so comparing results across them only goes so far.
Clinicians and families need consistent evidence on costs and equity before healthcare systems offer genomic screening to all newborns.
