Iron Total Binding Capacity (TIBC) Blood Test – $42

A TIBC (Total Iron Binding Capacity) test measures the maximum amount of iron that can be carried by proteins (mainly transferrin) in your blood. TIBC helps evaluate iron status when interpreted alongside serum iron and ferritin.

What This Test Measures

Total Iron Binding Capacity:
The total capacity of transferrin to bind iron. In iron deficiency, the body makes more transferrin trying to capture more iron, so TIBC increases. In iron overload, TIBC decreases.

Reference Range

Normal: 250-400 mcg/dL

Who Should Consider This Test

• Evaluating iron deficiency anemia
• Distinguishing causes of anemia
• Suspected iron overload (hemochromatosis)
• Monitoring iron status
• Follow-up to abnormal iron or ferritin

Interpreting Results

High TIBC:
• Iron deficiency – body increases binding capacity to capture limited iron
• Late pregnancy

Low TIBC:
• Iron overload (hemochromatosis)
• Chronic inflammation or infection
• Liver disease
• Malnutrition

Transferrin Saturation

TIBC is used to calculate transferrin saturation:
• Transferrin Saturation = (Serum Iron / TIBC) x 100

Normal saturation: 20-50%
• Low saturation (<20%): Iron deficiency • High saturation (>50%): Iron overload

Complete Iron Picture

For comprehensive iron assessment, evaluate together:
• Serum Iron – Current circulating iron
• TIBC – Iron carrying capacity
• Ferritin – Iron stores
• Transferrin Saturation – Percentage of capacity used
