Chromium Blood Test in California

What this test measures

Chromium is a trace element found in small amounts in many foods and in the environment. The body uses it in minute quantities, and it contributes to normal metabolism of carbohydrates and lipids. Because the amount needed is very small, both low and high levels can be a concern, and testing is used when a healthcare provider wants to assess chromium status or exposure.

The test measures chromium concentration in a blood sample, typically with a specialized method suited to trace elements. A single blood draw is collected from a vein, usually at the arm. Chromium can also be measured in urine, and sometimes both are used together to build a fuller picture of recent exposure and how the body is handling the mineral.

Results depend on collection technique and timing, because trace element testing is sensitive to contamination and to recent intake. Occupational or environmental exposure, supplements, and diet are all considered during interpretation. A healthcare provider evaluates the result with the clinical context, and this test is not a diagnosis on its own.
