SJC CLPPP: Providers


lead scannerNEW CDC blood lead reference value (BLRV) On October 28, 2021, the Centers for Disease Control and Prevention (CDC) announced a change in its blood lead reference value (BLRV) from ≥ 5 micrograms per deciliter (mcg/dL) to ≥ 3.5 mcg/dL. The CDC BLRV is used to identify children with higher levels of lead in their blood compared to most children. Children with blood lead levels at or above the BLRV represent those at the top 2.5% with the highest blood lead levels.

The CDC recommends healthcare providers follow-up BLLs ≥ 3.5 mcg/dL (the new BLRV), and California Department of Public Health encourages healthcare providers to provide retesting and follow-up for blood lead levels ≥ 3.5 mcg/dL.

The California Childhood Lead Poisoning Prevention Branch is working to update the California Management Guidelines to incorporate this change.

Lead Poisoning Overview

Most lead-poisoned children are asymptomatic. If present, symptoms typically are nonspecific complaints, such as stomachache, irritability, headache, fatigue, or loss of appetite. The only way to diagnose lead poisoning is to obtain a blood lead level (BLL).
