The Centers for Disease Control and Prevention wants all Flint kids, age six and under, to get a blood test for lead by April 1.
That's more than 8,000 kids, according to census data.
"That's a lot of kids to test,” says Dr. Nicole Lurie of the U.S. Department of Health and Human Services. “Testing is underway. And there are lots of places in this city, whether it's your doctors office, or other sites where you can get tested in the next two months."
The state says it's important to assume all kids who drank Flint water in the last two years were exposed to lead.
