Anemia is a condition that occurs when the amount of Hb in a person's blood drops below normal. Several routine laboratory tests may be used to help diagnose anemia as well as help to determine the underlying cause.
Depending on the results of these, the medical history of the person, and signs and symptoms, other tests may be done as follow up to help diagnose the cause of anemia and to help guide treatment. sTfR helps to distinguish between anemia caused by iron deficiency or by inflammation or chronic illness.
