LAS VEGAS— The Southern Nevada Health District is reminding parents and caregivers of the importance of testing children younger than 6 years of age for lead poisoning. Lead exposure can cause serious, lifelong health problems, and early detection through a simple blood test is the only way to know if a child has been exposed.

In 2024, 52 children in Clark County younger than 6 had blood lead levels at or above the Centers for Disease Control and Prevention (CDC) threshold of 3.5 micrograms per deciliter. Despite this, only an estimated 3.4 percent of children in the county are tested, based on information reported to the Health District. That means many cases go undetected.

“The science is clear: there is no safe level of lead,” said Dr. Cassius Lockett, District Health Officer of the Southern Nevada Health District. “Prevention and early detection are key to protecting children, as even low levels of lead can affect their learning and behavior. Parents should talk to their child’s health care provider about testing so we can take steps to safeguard their health and future.”

Medicaid and Nevada Check Up cover lead testing for beneficiaries at 12 months and again at 24 months, or any time before age 6 if earlier tests were missed. Parents and caregivers are strongly encouraged to ask their child’s provider about testing during well-child visits.

Lead is a naturally occurring heavy metal that has been detected in common consumer items including cookware, ceramics, keys, imported goods, herbal remedies, spices, fishing equipment, and even food. Over time, some of these items can degrade and release fine dust, contaminating homes and play areas without visible warning.

Childhood lead poisoning usually occurs when children ingest lead- contaminated dirt, dust, food, or items they put in their mouths.

Young children are especially vulnerable because their brains and nervous systems are still developing. Even low levels of lead can cause learning delays and behavior problems. Higher levels can cause headaches, hearing loss, brain damage, anemia, and even death. Because symptoms are often silent, a blood test is the only way to confirm exposure.
