An iron panel is a group of blood tests that shows how much iron is circulating in your blood, how much your body has in storage and how well iron is being transported to where it is needed. It usually includes serum iron, total iron-binding capacity (TIBC), transferrin saturation and ferritin. Read together, these four results can separate iron deficiency from iron overload and from anemia caused by inflammation, three situations that a hemoglobin result alone cannot tell apart. One result outside the range is common; the pattern is what matters.<\/p>
In this article you’ll learn what each test measures, the typical adult ranges, how to read the four results as a pattern, the most common causes of low and high iron, how to prepare for the test and when a result needs medical attention.<\/p>
Iron is needed to make hemoglobin, the protein in red blood cells that carries oxygen. According to MedlinePlus<\/a>, iron tests measure the iron in your blood, transferrin, the protein that moves iron around the body, how well iron attaches to transferrin and other proteins, and ferritin, which reflects how much iron is stored. Doctors order the panel to check for iron deficiency, to look for iron overload such as hemochromatosis and to follow treatment.<\/p> Some reports also list transferrin directly or the unsaturated iron-binding capacity (UIBC). The names iron studies, iron panel and full iron panel usually describe the same group of tests; full iron panel often signals that ferritin is included. To explore each result on its own, read our serum iron blood test guide<\/a> and check our gu\u00eda de niveles de ferritina en sangre<\/a>.<\/p> The most common reasons are tiredness, pale skin or shortness of breath, a low hemoglobin or small red cells on a blood count, heavy menstrual periods, pregnancy, a digestive condition that affects absorption and a family history of hemochromatosis. MedlinePlus notes that low iron may not cause symptoms until it is very low, which is why a doctor may order the test even when you feel fine. It is also used in liver disease and restless legs syndrome, and to check whether iron treatment is working.<\/p> Reference ranges vary between laboratories and units, so the range printed on your report is the one to use.
