Ordering Guidance


Urine is the preferred specimen type for determining nickel exposure and potential toxicity. Order NIU / Nickel, Urine or NICRU / Nickel/Creatinine Ratio, Random, Urine.

 

This test should not be ordered for the investigation of nickel hypersensitivity. Instead, order testing for lymphocyte proliferation to nickel.



Specimen Required


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

Supplies: Metal Free Specimen Vial (T173)

Collection Container/Tube: Royal blue-top (metal-free, no additive)

Submission Container/Tube: 7-mL Mayo metal-free, screw-capped, vial

Collection Instructions:

1. Allow the 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, screw-capped 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.
