Description:Key Points
• Lead exposures among newly arrived refugees may include environmental and occupational exposures, as well as household and personal items.
• Table 1 describes the lead screening recommendations for newly arrived refugee infants, children, adolescents, and pregnant and lactating women and girls.
• In October 2021, CDC lowered the blood lead reference value (BLRV) to 3.5 micrograms per deciliter (¬µg/dL) to identify children with higher levels of lead in their blood compared to most children. Capillary screening results at or above 3.5 Œºg/dL should be confirmed with blood drawn by venipuncture. The previous BLRV was 5 ¬µg/dL.
• This level is based on the on the 97.5th percentile of the blood lead distribution of US children aged 1-5 years from the National Health and Nutrition Examination Survey (NHANES). Children with blood lead levels at or above the BLRV are among the 2.5% of US children with the highest blood lead levels.
