Transferrin saturation determines an individual’s iron status by using the ratio of serum iron concentration and total iron-binding capacity (TIBC) as a percentage. The transferrin saturation test tells us how much iron in the blood is bound to transferrin. A low transferrin saturation usually indicates an iron deficiency, while a high saturation often confirms hemochromatosis.
It is recommended:In case of confirmed anaemia due to iron deficiency, which was detected in routine check-ups.It is determined by iron deficiency or overload in the body.To determine the capacity of the blood to transport iron.If you have any signs or symptoms of iron deficiency anaemia, like pallor, fatigue, weakness, and headaches.
The transferrin saturation test: Is ordered along with other iron tests when results from a routine complete blood count (CBC) show that a person's haemoglobin and hematocrit are low and the red blood cells (RBCs) are smaller and paler than normal.The iron studies test analyses three components, which include serum transferrin, iron serum, and total iron-binding capacity.Most of the iron is obtained from food and converted into haemoglobin in the RBCs, as only a small quantity of iron is required by the body.
The transferrin saturation test is prescribed by your doctor after completing the assessment of your conditions.
