Reference Interval:
0.0-4.9 µg/dL

| Interpretive Data: |
Elevated results may be due to skin or collection-related contamination, including use of a noncertified lead-free tube. Elevated levels of blood lead should be confirmed with a second specimen collected in a lead-free tube.
Sources of reference interval and interpretive comments include the CDC Guidelines for Screening Children for Blood Lead, 1997 and the Recommendations for Medical Management of Adult Lead Exposure, Environmental Health Perspectives, 2007. Thresholds and time intervals for retesting, medical evaluation, and response vary by state and regulatory body. Contact your State Department of Health and/or applicable regulatory agency for specific guidance on medical management recommendations.
| Concentration
| Comment
| | 5-9.9 µg/dL
| Adverse health effects are possible, particularly in children under 6 years of age and pregnant women. Discuss health risks associated with continued lead exposure. For children and women who are or may become pregnant, reduce lead exposure.
| | 10-19.9 µg/dL
| Reduced lead exposure and increased biological monitoring are recommended.
| | 20-69.9 µg/dL
| Removal from lead exposure and prompt medical evaluation are recommended. Consider chelation therapy when concentrations exceed 50 µg/dL and symptoms of lead toxicity are present.
| | Greater than 69.9 µg/dL
| Critical. Immediate medical evaluation is recommended. Consider chelation therapy when symptoms of lead toxicity are present.
