Blood tests are usually the initial test if there is a clinical suspicion of iron overload. Serum ferritin testing is a low-cost, readily available, and minimally invasive method for assessing body iron stores. However ferritin levels may be elevated due to a variety of other causes including obesity, infection, inflammation (as an acute phase ...
Normal reference ranges are: [citation needed] Serum iron: 60–170 μg/dL (10–30 μmol/L) Total iron-binding capacity: 240–450 μg/dL; Transferrin saturation: average 25%. [6] Reference ranges depend on multiple factors like age, sex, race and test devices. Most laboratories define “normal” as max. 30% for female and max. 45% for male ...
Measuring ferritin provides a crude measure of iron stores in the body. Fasting transferrin saturation values in excess of 45%, and the serum ferritin more than 250 ug/L in males and 200 ug/L in females are recognized as a threshold for further evaluation of haemochromatosis. [53]
Serum iron is a medical laboratory test that measures the amount of circulating iron that is bound to transferrin and freely circulate in the blood. Clinicians order this laboratory test when they are concerned about iron deficiency, which can cause anemia and other problems. 65% of the iron in the body is bound up in hemoglobin molecules in red blood cells.
Serum Iron: high; increased ferritin levels; decreased total iron-binding capacity; high transferrin saturation; Hematocrit of about 20-30%; The mean corpuscular volume or MCV is usually normal or low for congenital causes of sideroblastic anemia but normal or high for acquired forms.
Iron in ferritin or hemosiderin can be extracted for release by the RE cells, although hemosiderin is less readily available. Under steady-state conditions, the level of ferritin in the blood serum correlates with total body stores of iron; thus, the serum ferritin FR5Rl is the most convenient laboratory test to estimate iron stores.

Iron tests are groups of clinical chemistry laboratory blood tests that are used to evaluate body iron stores or the iron level in blood serum. Other terms used for the same tests are iron panel , iron profile , iron indices , iron status or iron studies .
The typical constellation of findings is indicative: The patients show a postprandial non-responsive and too low and static transferrin level (hypotransferrinemia) with high transferrin saturation (usually > 55 %) and low ferritin value. Multiple tests are obligatory due to physiologically induced fluctuations.
