Significance of test
Iron found in blood is mainly present in the hemoglobin of the RBC's. Its role in the body is mainly in the transportation of oxygen and cellular oxidation. Iron is absorbed in the small intestine, and bound to a globulin in the plasma, called transferrin and transported to the bone marrow for the formation of hemoglobin. Increased serum levels are found in hemolytic anemias, hepatitis, lead and iron poisoning. Decreased serum levels are found in anemias caused by iron deficiency due to insufficient intake or absorption of iron, chronic blood loss, late pregnancy and cancer. Increase in TIBC is found in Iron deficient anemias and pregnancy. Decrease in TIBC is found in hypoproteinemia, hemolytic/ pemicious/ sickle cell anemias, inflammatory diseases and cirrhosis.
