GENERAL HISTOLOGY

Detailed explanation-1: -At present there are three main parameters available to clinicians wishing to monitor iron status in their patients: serum ferritin and transferrin saturation (TFS), which are indirect measurements, and the percentage of hypochromic red cells, which directly reflects marrow iron status.

Detailed explanation-2: -In iron deficiency, the iron level is low but the TIBC is increased, thus transferrin saturation becomes very low. In iron overload states, such as hemochromatosis, the iron level will be high and the TIBC will be low or normal, causing transferrin saturation to increase.

Detailed explanation-3: -The two key tests to detect iron overload are: Serum transferrin saturation. This test measures the amount of iron bound to the protein transferrin that carries iron in your blood. Transferrin saturation values greater than 45% are considered too high.

Detailed explanation-4: -Another measurement, called transferrin saturation, checks how many places on your transferrin that can hold iron are actually doing so. Normal values are 15% to 50%. In severe cases of iron-deficiency and anemia, this number may fall below 10%. Many other health conditions can cause high or low levels of transferrin.
