Chromium
Essential trace element from food, involved in fat and carbohydrate metabolism
Definition
Chromium is an essential trace element that the body cannot make itself and must obtain from food. It is involved in breaking down fats and carbohydrates and supports the action of insulin. Good sources are brewer's yeast, meat and whole grain products; eggs, liver, oysters, wheat germ, broccoli and some fruits, vegetables and spices also provide chromium.

↓ What a low value means
According to MedlinePlus, chromium deficiency may occur in people with impaired glucose tolerance, for example older adults with type 2 diabetes or infants with protein-calorie malnutrition. Symptoms alone cannot tell you whether a deficiency is present. A chromium supplement is not a stand-alone treatment for diabetes; discuss any questions with your doctor.
↑ What a high value means
Excess chromium is uncommon: the body absorbs only small amounts and excretes it quickly, so toxicity is rare. An unusual value in a lab report should still be interpreted by a doctor, for example with regard to supplements you take.
When to test
Chromium is mainly known as a nutrient from food. Whether a blood measurement makes sense in your situation, and what preparation your lab requires, is something to clarify with your doctor; mention any supplements you take.
