How do you calculate total iron binding capacity?

Accordingly, what does total iron binding capacity?

Definition. Total iron binding capacity (TIBC) is a blood test to see if you have too much or too little iron in your blood. Iron moves through the blood attached to a protein called transferrin. This test helps your health care provider know how well that protein can carry iron in your blood.

Also Know, why is total iron binding capacity high in iron deficiency anemia? Transferrin, a protein that transports iron, is elevated in iron-deficiency anemia, indicating that the body needs more iron. TIBC tends to be increased when iron stores are diminished and decreased when they are elevated. In iron-deficiency anemia, the TIBC is higher than 400–450 mcg/dL because stores are low.

Accordingly, what does it mean if your total iron binding capacity is high?

Total Iron Binding Capacity Test Results This may be caused by a lack of iron in the diet, increased blood loss during menstruation, pregnancy, or a chronic infection. A total iron binding capacity value below 240 mcg/dL usually means that there's a high level of iron in your blood. This may be caused by: liver damage.

What causes low TIBC?

Lower-than-normal TIBC may mean:

• Anemia due to red blood cells being destroyed too quickly (hemolytic anemia)
• Lower-than-normal level of protein in the blood (hypoproteinemia)
• Inflammation.
• Liver disease, such as cirrhosis.
• Malnutrition.
