17 Απρ 2024 · A patient’s blood lead level (BLL) is measured in micrograms of lead per deciliter of blood (μg/dL). Healthcare providers should follow recommendations based on initial screening capillary and confirmed venous BLLs. Learn more about the recommended actions after a blood lead level test.
2 Απρ 2024 · Children with blood lead levels at or above the BLRV represent those at the top 2.5% with the highest blood lead levels. The documents below refer to a blood-lead level of 10 micrograms per deciliter (μg/dL) as the CDC level of concern for adverse health outcomes in children.
2 Απρ 2024 · As of October 28, 2021, CDC uses a blood lead reference value (BLRV) of 3.5 micrograms per deciliter (µg/dL) to identify children with blood lead levels that are higher than most children’s levels.
The current CDC reference level is 3.5 micrograms per deciliter of lead in blood for children. What has not changed: the need to find the source of lead in children with all elevated blood lead levels so that exposure can be stopped.
Experts now use an upper reference level value of 97.5% of the population distribution for children’s blood lead, based on the National Health and Nutrition Examination Survey (NHANES) estimate of the distribution of BLLs in children ages 1-5 years.
Lead is associated with negative outcomes in children, including impaired cognitive, motor, behavioral, and physical abilities. In 1991, CDC defined the blood lead level (BLL) that should prompt public health actions as 10 μg/dL.
In this report we provide information to help clinicians understand blood lead levels < 10 microg/dL, identify gaps in knowledge concerning lead levels in this range, and outline strategies to reduce childhood exposures to lead.
