Iron (Fe)

What To Think About

• Taking iron supplements for tiredness can mask an iron problem. Talk to your doctor about taking iron supplements.
• Iron levels change during the day. Iron tests are best done in the morning, when iron levels are highest.
• The results of an iron test are also checked with results of a complete blood count (CBC), ferritin, and transferrin tests. The ferritin test is often better than an iron test to see whether iron deficiency is present. An iron test and ferritin test are often done at the same time. For more information, see the medical tests Complete Blood Count (CBC) and Ferritin.
• A test called the siderocyte stain test checks the number of red blood cells that have particles of iron not bound to hemoglobin (siderocytes). Normally, very low numbers of siderocytes are present in blood. High levels of siderocytes in adults may mean a type of anemia, iron overload, lead poisoning, hemochromatosis, or a severe infection are present.
• When iron deficiency anemia is diagnosed, the source of the anemia must be found and treated. Iron deficiency can be caused by long-term (chronic) blood loss from heavy menstrual bleeding, pregnancy, not enough iron in the diet, or bleeding inside the intestinal tract (from ulcers, colon polyps, colon cancer, hemorrhoids, or other conditions). In rare cases, too much iron may be lost through the skin (because of a disease such as psoriasis) or in the urine. Iron deficiency anemia can be easily treated with iron supplements, but the key is to identify it and stop the iron loss.
• Hemochromatosis can be treated with medicines to help the body get rid of extra iron. A procedure called a phlebotomy can also be done to remove iron from the body.
