If you need to know which are the transferrin saturation reference ranges or you require more information about the role of transferrin saturation in the blood you can visit: Normal transferrin saturation level in the blood
The transferrin saturation is an index to measure the percentage of iron that is being transported of the total amount that transferrin can carry through the bloodstream.
A low percentage of transferrin saturation may be a sign of iron deficit in the body. It is suggestive of some types of anemia and it is usually correlated with a low level of hemoglobin.
The types of anemias that shows a low percentage of transferrin saturation are iron-deficiency anemia and anemia of the chronic disease.
The transferrin saturation is a bit low and may be a sign of mild or moderate anemia.
In case of suffering iron-deficiency anemia, serum iron may be low (below 60 µg/dL), ferritin in the blood may be low and TIBC (total iron binding capacity) will be high (above 400 µg/dL).
In case of suffering an anemia of chronic disease the serum iron will be low, TIBC will be in the normal range or a bit low and ferritin in the blood in the normal range or a bit high.
The transferrin saturation percentage is very low. It may suggest the existence of an iron-deficiency anemia.
In case of iron-deficiency anemia, serum iron may be low (below 40 µg/dL), ferritin in the blood may be low (below 10 ng/dL) and TIBC (total iron binding capacity) will be high.
The transferrin saturation percentage could be near 0 % in severe anemia.
There are some circumstances than can reduce your transferrin saturation:
Lower than normal transferrin saturation can be due to:
