What Iron, Serum measures

The amount of iron circulating in blood at the moment of sampling, bound to its transport protein.

What a high Iron, Serum means, and common causes

Serum iron is above range. It fluctuates through the day and after iron tablets, so a single high value means little on its own.

Common causes: Iron supplements taken shortly before the sample, repeated transfusions, haemochromatosis, liver disease, and haemolysis.

What a low Iron, Serum means, and common causes

Serum iron is below range, which is consistent with iron deficiency but is not reliable enough to diagnose it alone.

Common causes: Iron deficiency from blood loss or poor intake, long-standing inflammation, and recent infection.

Frequently asked questions

Roughly 65 to 175 mcg/dL for men and 50 to 170 mcg/dL for women.

Serum iron swings with the time of day and with what you ate or took that morning. Ferritin reflects stored iron and is far more stable.

Total iron binding capacity measures how much spare capacity your blood has to carry iron. It rises in iron deficiency, which helps confirm the diagnosis.

Ferritin aur TIBC bhi dekhein. Sirf serum iron se kami pakki nahin hoti, aur kaaran dhoondhna zaroori hai.
