According to CDC guidance, at what blood lead level is a health risk considered for children?

• A. 5 ug/dL
• B. 80 ug/dL
• C. 10 ug/dL
• D. 50 ug/dL

Answer: (A)

Lead exposure can harm children even at very low levels, but the CDC uses a specific trigger to identify elevated exposure. A blood lead level of 5 micrograms per deciliter or higher is the reference value that flags an elevated BLL and prompts public health actions to identify sources of exposure and reduce risk. This threshold comes from national data and serves as the standard point for surveillance and intervention. While lower levels can still be harmful, 5 μg/dL is the recognized benchmark for considering health risk and initiating follow-up.
