Understanding Your Iron Panel
The iron panel measures how much iron is in your blood and stored in your body. It is used to check for both iron deficiency (too little) and iron overload (too much).
What the Iron Panel Measures
Iron is essential for making healthy red blood cells and carrying oxygen. This panel looks at iron from several angles for a complete picture.
| Component | What It Means |
|---|---|
| IronSerum Iron | The amount of iron circulating in your blood right now. |
| Ferritin | Your body’s iron storage. Low ferritin is the earliest and most reliable sign of iron deficiency; very high ferritin can point to iron overload or inflammation. |
| TIBCTotal Iron-Binding Capacity | A measure of your blood’s capacity to carry iron. It tends to rise when iron is low. |
| Transferrin Saturation% Saturation | The percentage of your iron-carrying capacity that is actually filled. Low saturation suggests deficiency; high saturation can suggest overload, as in hemochromatosis. |
What’s Most Important to Know
Ferritin and transferrin saturation are the two values we watch most closely. Together they help tell the difference between iron deficiency and iron overload.
Ferritin can also rise with infection or inflammation, so we interpret it in context. If your panel suggests iron overload, Dr. Mui may recommend testing for hemochromatosis.
