6/23/22, 10:26 AM CDC updates blood lead reference value | Lead | CDC https://www.cdc.gov/nceh/lead/news/cdc-updates-blood-lead-reference-value.html#:~:text=CDC updates blood lead reference value to 3.5 µg%2FdL&text=CDC uses a blood lead,higher than most children's levels.4/6 Despite the overall decline of blood lead levels over time, lead exposure remains a signicant public health concern for some young children because of persistent lead hazards in the environment and hand to mouth activity that is common among this age group. Sources of lead include lead-based paint, lead service lines, lead in household plumbing material, and soil contaminated by past sources, such as automobile gasoline and hazardous waste sites. Young children can also be exposed to lead in contaminated food, folk remedies, cultural products, and consumer products. Young children can also be exposed to lead secondhand if a parent or other adult they spend time with works or engages in recreational activities that involve lead or lead-based products. How might health departments use this new level?Health departments may use the blood lead reference value (BLRV) in recommendations that involve follow-up evaluation of young children under 6 years, after blood lead level testing. They can use the reference value to identify high-risk populations and geographic areas most in need of lead exposure prevention. Health departments can guide targeted interventions to reduce lead exposure in children by identifying hotspots for potential lead exposure and prioritizing where to focus blood lead screening, outreach, and community interventions. CDC’s BLRV is a screening tool to identify children who have higher levels of lead in their blood compared with most children. The reference value is not health-based and is not a regulatory standard. States independently determine action thresholds based on state laws, regulations, and resource availability. CDC encourages healthcare providers and public health professionals to follow the recommended follow-up actions based on conrmed blood lead levels. What might this new level aect laboratory reporting?The Division of Laboratory Sciences in CDC’s National Center for Environmental Health compiled and reviewed laboratory prociency data [PDF – 828 KB] through the Lead and Multi-element Prociency Program. It concluded that current available laboratory tests for measuring blood lead can reliably measure blood lead levels of 3.5 μg/dL and greater. CDC will continue to assist laboratories, healthcare providers, and health departments to overcome the challenges of measuring and managing lower levels of blood lead in children. CDC developed a template for clinical laboratories to report blood lead test results on the blood lead laboratory report. This reporting template identies the BLRV and delineates risk-based intervals that represent escalating priorities for public health and medical intervention.  What does this mean for healthcare professionals?Healthcare professionals should interpret the blood lead levels (BLLs) of their patients in accordance with the updated blood lead reference value (BLRV). They should then determine the need for follow-up testing and interventions for those children identied with BLLs at or above the BLRV. CDC has developed outreach materials to assist healthcare professionals. These can be found on our healthcare provider’s webpage. What does this mean for parents of children who test above 3.5 µg/dL?
