Reference Range

COMPONENT REFERENCE INTERVAL

Lead, Whole Blood < 6 years: <3.5 μg/dL

In 2021, CDC revised the blood lead reference
level for children ages 1-5 years to less than
3.5 ug/dL. Children with levels at or above this
value represent those at thetop 2.5% of
blood levels.

CDC recommendations for clinical follow up
and lead level monitoring may vary
depending on initial measured lead level and
the child's age. Local and state health
departments also may have different
recommendations for monitoring and
clinical follow up. Please consult your local
or state health department, or the CDC's
website regarding monitoring of lead levels in
children:

COMPONENT REFERENCE INTERVAL

Lead, Whole Blood >= 6 years: < 5.0 μg/dL

CDC recommendations for clinical follow up and lead
level monitoring may vary depending on initial measured
lead level and the patient's age. Local and state
health departments also may have different
recommendations for monitoring and clinical follow up.
Please consult your local or state health department,
or the CDC's website regarding monitoring
of lead levels in adults:
