Review Updated Childhood Blood Lead Screening Guidelines

The California State Department of Public Health’s (CDPH’s) Childhood Lead Poisoning Prevention Branch has released updated guidance for medical providers. In summary:

  • Test all children at one and two years old – and test children older than two who have never been tested. 
  • The lead test must be venous.
  • Children who test positive for elevated blood lead level (BLL) need treatment: see instructions.

Screening other patient populations

  • For recently arrived refugees six months to six years old, the Centers for Disease Control and Prevention (CDC) offers this lead screening guidance:
    • Test for BLL within 90 days of arrival to the US (and preferably within 30 days). 
    • Conduct a follow-up lead test within three to six months post-resettlement, regardless of initial BLL screening results.   
  • For patients who are pregnant, CDC guidelines recommend conducting a blood lead test when there has been potential lead exposure. Also explain the importance of avoiding lead exposure during pregnancy due to the dangers, which include:
    • Increased risk of miscarriage, premature birth and low birth weight. 
    • Harm to the baby’s brain, kidneys and nervous system. 
    • Childhood learning and/or behavior problems.
