Lead (Venous)
Test Code599
CPT Codes
83655
Preferred Specimen
3 mL whole blood collected in a K2 EDTA (tan-top) tube
Minimum Volume
0.5 mL
Other Acceptable Specimens
Whole blood collected in: Sodium heparin, lead-free (tan-top) tube, EDTA (royal blue-top) tube, sodium heparin (royal blue-top) tube, or EDTA (lavender-top) tube
Instructions
Collection material such as alcohol swabs should be lead-free. Use powderless gloves. Once washed, fingers must not come into contact with any surface. Clean skin (area for venipuncture) with lead-free alcohol swab prior to puncture. Avoid worksite collection.
Tests performed on a specimen submitted in a non-trace element tube or non acid-washed/non metal-free container may not accurately reflect the patient's level. If a non-trace element tube/container is received, it will be accepted for testing. However, elevated results shall be reported with a message that re-submission with a trace element tube/container is recommended.
