Chromium(VI) in Serum or Plasma (Mass Concentration)
This test measures the amount of hexavalent chromium (Cr VI), a toxic form of chromium, in your blood. Chromium is often found in industrial products and can be harmful if present in high levels.
["Chromium(VI) is a potential environmental toxin that may affect your health if detected in your blood."]

What Is Chromium(VI)?
Chromium exists in several forms in nature, but hexavalent chromium (Cr VI) is particularly dangerous. This form can cause respiratory issues, skin irritation, and other health problems when inhaled or absorbed through the skin. In blood tests, it’s important to monitor levels to assess exposure risks.
Why Might You Need This Test?
Your healthcare provider may order this test if you have occupational exposure to chromium, live in an area with industrial pollution, or have symptoms like skin rashes, breathing difficulties, or chronic fatigue. It’s also used in cases of suspected poisoning or environmental contamination.
How Is the Test Performed?
A blood sample is drawn from a vein, typically in your arm. The sample is then sent to a lab for analysis using a specialized technique to measure chromium(VI) concentration. Results are reported in micrograms per deciliter (µg/dL) or another appropriate unit.
What Do the Results Mean?
High levels of chromium(VI) in the blood may indicate recent exposure to industrial or environmental sources. Low or normal levels suggest no significant exposure. Your doctor will interpret results in the context of your medical history and symptoms.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Elevated chromium(VI) levels can signal occupational hazards, such as working near metal processing plants or chemical factories. Chronic exposure may lead to long-term health risks, including lung damage or cancer. If you’ve had exposure, follow-up testing may be recommended to monitor your health.
