What is this test?
This panel measures the concentration of chromium and cobalt, two trace metals, in a blood sample. The results can provide information about recent or ongoing exposure.
Why might I need this test?
The test may be ordered to evaluate exposure related to work, contaminated products, supplements, or medical devices such as metal joint implants. It may also be used to monitor patients who have devices that release these metals.
How is the test performed?
A blood sample is collected and analyzed in the laboratory using methods designed to measure very small concentrations of chromium and cobalt. Results are reported as mass concentrations, or the amount of each metal per unit volume of sample.
How do I prepare for the test?
Follow your clinician's instructions. Tell the laboratory if you have recently had surgery involving a metal implant or if you have occupational or environmental exposure to chromium or cobalt, because these factors can affect interpretation.
Reference range
Adult males: 7-56 U/L; Adult females: 7-43 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Higher-than-expected chromium or cobalt levels may indicate recent exposure to these metals, including exposure from certain workplaces, products, supplements, or medical implants. Results must be interpreted with symptoms, exposure history, and other laboratory findings. A result alone does not establish metal poisoning or a specific diagnosis.
Short name
Chromium and Cobalt Panel
Frequently asked questions
What does this test measure?
Why are both metals tested together?
Do high levels always mean metal poisoning?
