| Title | IRON-BINDING CAPACITY, UNSATURATED (TIBC) Includes Iron and % Saturation (Transferrin) |
| Specimen Requirement | <p>1 SST/2.0 mL serum. After 30 minutes of clotting, promptly centrifuge and refrigerate serum.</p> |
| Methodology | Spectrophotometry |
| Stability | Room Temp: 4 days; Refrigerated: 7 days |
| Reference Range | 155-300 ug/dL |
| Turnaround | 1 day |
| Clinical Use | <p>Serum iron concentration connotes the Fe (III) bound to serum transferrin and does not include the iron contained in serum as free hemoglobin. Because normally only about one third of the iron binding sites of transferrin are occupied by Fe (III), serum transferrin has considerable reserve iron binding capacity.</p> |
| Test Code | TIBC |
