The state of Maryland will expand its testing for lead poisoning to all one- and two-year-old children in the state, regardless of where they live, the administration of Gov. Larry Hogan (R) announced. Currently, the state requires testing only for children enrolled in Medicaid or living in Baltimore and other at-risk areas. Under the new regulations, providers will be responsible for ensuring that children undergo testing at the appropriate ages, and parents will have to provide proof of lead-poisoning testing when their children enter licensed day-care programs or public pre-kindergarten, kindergarten or first grade. Insurance providers and patients will cover the screening costs. A recent study by Maryland's Department of Health and Mental Hygiene and Department of the Environment showed that every jurisdiction in the state has at least some children with lead levels exceeding the CDC's recommendation of 5 micrograms per deciliter of blood.
