Notes
Capillary blood levels greater than 4.9 µg/dL may be contaminated from lead |
found on the finger surface and require confirmation with venous blood. |
The use of non-certified lead-free tubes might produce a falsely elevated |
result and repeat testing in a Tan Top certified lead free tube is recommended prior |
to initiating chelation or conducting environmental investigation of potential lead |
sources. |
To minimize Lead Contamination: |
1. Keep the collection area clean and dust free. |
2. Clean the venipuncture site with alcohol, not iodine. |
3. Do not ream out or remove blood clots from collection tube. |
4. Do not insert any objects into the specimen tube or pour off the sample. |
