Chromium, Serum
Use
Occupational exposure and exposure to environmental contamination of chromium may lead to toxicity. The need for chromium supplements is unproven. Supplements taken in excess can lead to toxicity.
Special Instructions
Draw one (royal blue‑top) tube of blood and discard. Draw second (royal blue‑top) tube. Allow blood to clot in an upright position. Centrifuge and pour (do not pipette) the serum into a metal‑free tube. 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 are reported with the message that resubmission with a trace element tube/container is recommended. High concentrations of gadolinium and iodine are known to interfere with most metals tests. If either contrast media has been administered, a specimen should not be collected for 96 hours.
