Chromium, Serum
Also known as: CR S
Use
This test is useful in assessing chromium deficiency or overload. Elevated serum chromium levels can be associated with metal-on-metal total hip replacement implants. Chromium levels should be interpreted in the context of the overall clinical scenario, especially in patients with metal-on-metal prosthetics. For the assessment of hexavalent chromium exposure, Chromium, RBC (2014505) is preferred.
Special Instructions
Not provided.
Limitations
Elevated serum chromium levels may occur due to contamination from skin or collection-related issues, such as the use of noncertified metal-free collection containers. High serum chromium levels may also occur in asymptomatic patients with metal-on-metal prosthetics and should be carefully evaluated.
