EPIC Test Procedure Code: LAB3249

Synonyms:
ZN_S
Performing Lab:
Referral Laboratory
Patient Preparation:

High concentrations of gadolinium, iodine, and barium are known to interfere with most metal tests. If gadolinium-, iodine, or barium-containing contrast media has been administered, the specimen should not be collected for 96 hours.

Container Type:
Navy blue top (without EDTA) tube
Specimen Type:

Serum

Preferred Volume:
0.8 mL
Minimum Volume:
0.2 mL
Collection Procedure:

1. This specimen must always be drawn first. 

2. Do not collect specimen from a line. 

3. Allow the specimen to clot for 30 minutes; then centrifuge the specimen to separate serum from the cellular fraction. Serum must be removed from cellular fraction within 4 hours of specimen collection. Avoid hemolysis. 

4. Remove the stopper. Carefully pour specimen into a Mayo metal-free, polypropylene vial, avoiding transfer of the cellular components of blood. Do not insert a pipet into the serum to accomplish transfer, and do not ream the specimen with a wooden stick to assist with serum transfer. 

5. See Metals Analysis Specimen Collection and Transport for complete instructions.

Specimen Processing:

Separate the plasma or serum from the cells within 4 hours of collection and transfer to a metal free pour off tube.
