LEAD, BLOOD, QUANTITATIVE

Specimen Required
Draw blood in a dark-blue EDTA tube. Send 1.0 mL whole blood (0.2 mL minimum) refrigerated. Care should be used in collecting specimens to avoid contamination because lead is widely distributed in the environment.
A completed lead requisition must accompany sample.

Alternate Specimen
Whole blood: Lavender EDTA, K2EDTA (brown top). If sample is drawn capillary, indicate on tube.

Rejection Criteria
Clotted samples

Methodology
Atomic Absorption Spectrophotometry

Stability
Room Temperature: 7 days; Refrigerated: 1 month; Frozen: Not Recommended

Reference Range
Blood lead in children (according to CDC Classification < or = 15 years)
Blood Lead   Comment   
<5 ug/dL   No action required.   
CDC recommendations for clinical follow up and lead level monitoring may vary depending on initial measured lead level and the child's age.

Please consult your local or state health department, or the CDC's website regarding monitoring of lead levels in children:

*Elevated levels of blood lead should be confirmed with a second specimen before remedial action is instituted.
Elevated capillary blood specimens should be repeated using a venous specimen due to possible contamination.
Adults   >16 years   
Blood Lead   Comment   
<5.0 ug/dL   No action required.
