CDPH Lead Inspector/Assessor California State Practice Exam

What is the interpretation of a venous confirmed blood lead level of 15-19ug/dL for a child under 6?

1. No significant exposure

2. Some exposure to lead

3. Lead poisoning confirmed

4. Serious lead poisoning

The correct answer is: Some exposure to lead

A venous confirmed blood lead level of 15-19 micrograms per deciliter (ug/dL) indicates that a child has been exposed to lead, but it does not meet the criteria for lead poisoning or serious lead poisoning. This range suggests that there is some degree of exposure to lead that warrants concern and potentially requires further evaluation and intervention. In clinical practice, levels considered at least moderately concerning typically start at 10 ug/dL, and while 15-19 ug/dL indicates that there is a risk involved, it does not classify as lead poisoning outright, which is defined as levels of 20 ug/dL and above in many guidelines. Therefore, this blood lead level reflects a need for follow-up and potential investigation into the sources of lead exposure to prevent any escalation in lead levels. Making the interpretation aligns with both clinical guidelines and public health recommendations regarding lead exposure in children.
