Chromium is a mineral that the body uses in small doses for typical body functions, like digesting food. It also helps to move glucose into cells to use as energy, as well as to turn carbohydrates, fats, and proteins into energy. This blood test is used to determine chromium levels.
A blood sample is needed. Most of the time blood is drawn from a vein located on the inside of the elbow or the back of the hand.
You may feel slight pain or a sting when the needle is inserted. You may also feel some throbbing at the site after the blood is drawn.
You should stop taking mineral supplements and multivitamins for at least several days before the test. Ask your health care provider if there are other medicines you should stop taking before testing. Also, let your provider know if you have recently had contrast agents containing gadolinium or iodine as part of an imaging study. These substances can interfere with testing.
The serum chromium level normally is less than or equal to 1.4 micrograms/milliliter (µg/mL) or 26924.80 nanomoles/L (nmol/L).
Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test result.
