A ferritin blood test measures the level of iron in the blood, and normal levels should fall within the range of 12 to 300 nanograms per milliliter of blood for men and 12 to 150 nanograms per milliliter of blood for women, as reported by MedicineNet. Acceptable normal values may vary slightly depending on the laboratory where the blood sample was sent to for review. High levels of iron indicate that the patient is suffering from an iron storage disorder, like hemochromatosis, or an alcoholic liver disease, while low levels of iron indicate that the patient may be struggling with an iron deficiency, which is the main cause for anemia and intestinal conditions that cause poor iron absorption.
To prepare for the test, some medical professionals may request patients to fast for a minimum of 12 hours. In addition, some experts also recommend performing the test in the morning for the most accurate results possible.
Iron is a crucial element required in the body. It is needed for red blood cell production. Red blood cells are responsible for providing and distributing oxygen to all of the tissues throughout the body for aerobic respiration, which is a process that helps produce more energy.
