Any detectable blood lead levels, even below 3.5 µg/dL, are associated with subclinical effects such as inattention, hyperactivity, and decreased cognitive function on a population level. Health Care professionals can provide education that even low blood lead levels are associated with developmental delays, difficulty learning, and behavioral issues. However, a blood lead level does not mean a child will develop these conditions. The evidence for harmful effects is based on data drawn from populations of exposed children and is not intended to be interpreted at the level of the individual child. It may be helpful to explain to families that while children with blood lead levels are more likely to experience certain health effects, it does not necessarily mean that their child will. Explain to the family that the potential health outcomes are multifactorial or impacted by many factors. Reassure parents that there is evidence for the positive impacts of proactive measures for promoting healthy brain development, such as providing a stimulating and safe environment, adequate sleep, early education, and good nutrition. You may also share that early educational interventions have been shown to reduce lead-related harm and provide referrals to services for children with BLLs above the CDC reference value, if available.
