Quick answer
The chromium blood test measures the level of chromium in the blood. Chromium is an essential trace mineral that the body needs in very small amounts, and it plays a role in how the body uses carbohydrates and fats. The test can help evaluate a possible deficiency or excess exposure, and results are interpreted with the person's history by a qualified healthcare provider.
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.
- Chromium (blood concentration)
- Serum or whole blood chromium
- Reference range comparison for chromium
- Related trace elements when ordered together (such as zinc, copper, or selenium)
- Complete blood count when included in the same order
- Metabolic markers when part of a broader evaluation
Why people order this test
- Assess possible chromium deficiency
- Evaluate suspected excess exposure or toxicity
- Support monitoring in an occupational or environmental exposure setting
- Check chromium status when nutritional concerns are present
- Follow up on a previously abnormal trace element result
- Provide context for a metabolic or nutritional evaluation
How to prepare
No fasting is usually required, but the laboratory may ask for a morning collection or provide specific instructions. A blood sample is drawn from a vein, usually at the arm. Tell the ordering provider about supplements and any work related exposure, since these can affect results.
Understanding your results
Results are typically available within one to three business days. The report shows the chromium level, which is compared with the laboratory reference range. Values outside the range may reflect deficiency, excess exposure, or collection factors, so a qualified healthcare provider interprets them in context.

Frequently Asked Questions
What is chromium and why is it tested?
Chromium is a trace mineral the body needs in very small amounts for normal metabolism. Testing can help assess whether levels are too low or too high.
Do I need to fast for a chromium blood test?
Fasting is not usually required. Follow any collection instructions from the laboratory, and mention supplements or possible exposure to the ordering provider.
Can diet affect the result?
Yes. Recent intake and supplements can influence chromium levels, so the laboratory and provider may ask about diet and supplement use when interpreting the result.
How is the sample collected?
A blood sample is drawn from a vein, usually at the arm. Trace element testing requires careful collection to avoid contamination.
Does this test diagnose a condition?
No. It measures a level that a qualified healthcare provider interprets with other information. It is not a diagnosis on its own.
