Transferrin saturation, abbreviated as TSAT and measured as a percentage, is a medical laboratory value. It is the ratio of serum iron and total iron-binding capacity, multiplied by 100. Of the transferrin that is available to bind iron, this value tells a clinician how much serum iron are actually bound. For instance, a value of 15% means that 15% of iron-binding sites of transferrin are being occupied by iron. For an explanation of some clinical situations in which this ratio is important, see Total iron-binding capacity. The three results are usually reported together. ==Usual values== Normal reference ranges are: * Serum iron: 60–170 μg/dl (10–30μmol/L) * TIBC: 240–450 μg/dl * Transferrin saturation: 15–50% (males), 12–45% (females) μg/dl = micrograms per deciliter. Laboratories often use different units and "normal" may vary by population and the lab techniques used. Look at the individual laboratory reference values to interpret a specific test (for instance, your own). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Transferrin saturation」の詳細全文を読む スポンサード リンク
