Instructions
Collection Instructions: Draw one royal blue-top tube of blood and discard. Draw second royal-blue top tube. Allow to clot in an upright position. Centrifuge and pour (do not pipette) the serum into a metal-free tube.


Transport Container
Preferred: 2 mL serum collected in a no additive (royal blue-top) tube

Minimum: 1 mL

Alternative: 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 a re-submission with a trace element tube/container is recommended.


Transport Temperature
Room temperature.


Specimen Stability
Room temperature: 5 days; Refrigerated: 10 days; Frozen: 21 days


Methodology
Inductively Coupled Plasma/Mass Spectrometry (ICP/MS)

Setup Schedule
