What is Chromium?

A trace mineral, and this test measures how much of it is in your blood.

Chromium is found in very small amounts in the body and plays a minor role in how the body handles sugar and fat. Blood chromium is most often measured to check for exposure, for example in people with certain metal joint implants, rather than for nutrition. A higher than expected level can be associated with wear from metal implants or workplace exposure. It is a specialized test and not part of a general checkup.
