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 .
Transferrin saturation (TS), measured as a percentage, is a medical laboratory value. It is the value of serum iron divided by the total iron-binding capacity [1] of the available transferrin, the main protein that binds iron in the blood, this value tells a clinician how much serum iron is bound.
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.
Transferrin (mg/dL) = 0.7 x TIBC (μg of iron/dL) To measure TIBC in the blood is less expensive than a direct measurement of transferrin. [4] [5] The TIBC should not be confused with the unsaturated iron-binding capacity or UIBC (LOINC 2501-5, 22753-8 & 35216-1). The UIBC is calculated by subtracting the serum iron from the TIBC. [6]

However, a varied size distribution of red blood cells is a hallmark of iron deficiency anemia, and as such shows an increased RDW in virtually all cases. In the case of both iron and B 12 deficiencies, there will normally be a mix of both large cells and small cells, causing the RDW to be elevated.
GPnotebook is a British medical database for general practitioners (GPs). [1] It is an online encyclopaedia of medicine that provides an immediate reference resource for clinicians worldwide.
Iron is also stored as a pigment called hemosiderin, which is an ill-defined deposit of protein and iron, created by macrophages where excess iron is present, either locally or systemically, e.g., among people with iron overload due to frequent blood cell destruction and the necessary transfusions their condition calls for. If systemic iron ...
