Collection Container/Tube: Plain, royal blue-top Vacutainer plastic trace element blood collection tube (T184)

Submission Container/Tube: 7-mL Mayo metal-free, screw-capped, polypropylene vial (T173)

Specimen Volume: 1.6 mL

Collection Instructions:

1. Allow specimen to clot for 30 minutes; then centrifuge the specimen to separate serum from the cellular fraction.

2. 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.

3. See Trace Metals Analysis Specimen Collection and Transport in Special Instructions for complete instructions.

Additional Information:

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

2. If ordering the trace element blood collection tube from BD, order catalog #368380.
