Storage/Transport Temperature
Room temperature. Also acceptable: Refrigerated. 
Unacceptable Conditions
Serum. Heparinized or clotted specimens. 
Trace Elements requisition form may be required (ARUP form #32990). 
If the specimen is drawn and stored in the appropriate container, the trace element values do not change with time. Ambient: Indefinitely; Refrigerated: Indefinitely; Frozen: Unacceptable 
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.

Information sources for reference intervals and interpretive comments include the "CDC Response to the 2012 Advisory Committee on Childhood Lead Poisoning Prevention Report" 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.

All ages5-9.9 µg/dLAdverse 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.
All ages10-19.9 µg/dLReduced lead exposure and increased biological monitoring are recommended.
All ages20-69.9 µg/dLRemoval 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.
Less than 19 years of ageGreater than 44.9 µg/dLCritical. Immediate medical evaluation is recommended. Consider chelation therapy when symptoms of lead toxicity are present.
Greater than 19 years of ageGreater than 69.9 µg/dLCritical. Immediate medical evaluation is recommended. Consider chelation therapy when symptoms of lead toxicity are present.
