When should lead screening begin in children?

1. 6 months

2. 12 months

3. 18 months

4. 24 months

The correct answer is: 6 months

Lead screening in children is recommended to begin at 6 months of age, particularly for those at higher risk of exposure to lead. This early screening is crucial because lead exposure can have significant developmental effects, including impacts on cognitive functioning and overall health. The Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics (AAP) emphasize the importance of identifying children who may be at risk due to environmental factors, socioeconomic status, or other influences. By starting at 6 months, healthcare providers can ensure timely intervention if elevated blood lead levels are detected, thereby reducing the potential for long-term adverse outcomes associated with lead poisoning. As children grow older, additional screenings may be recommended at subsequent well-child visits, particularly at 12, 18, and 24 months, depending on risk factors and local health guidelines. However, initiating screening at 6 months is fundamental in catching potential exposure early.
