"It doesn't take too many of those kids to win back the cost of the entire screening program," Vockley said. "It's very cost-effective."
Vockley said he's glad for the state mandates because they might make it easier to garner resources to treat infants, but he pointed out that a lot of hospitals were doing the screening tests long before they became required by their state.
Howse recommended that expectant parents check with their doctor to find out what screening tests are done in the hospital and, if the testing doesn't cover all 29 conditions, that parents arrange to have the additional tests done.
