High Serum Iron: what it means

A Serum Iron result above the normal range is considered high. Here is what a raised Serum Iron can point to, and when it is worth discussing with a doctor.

Reference range: 60–170 µg/dL (men); 50–170 µg/dL (women); diurnal variation up to 30%

What a high Serum Iron can mean

  • Haemochromatosis — hereditary iron overload; TSAT often >45%, ferritin elevated.
  • Recent iron supplementation or transfusion — confounds the value for ~24 hours.
  • Liver disease — hepatocyte release of iron stores.
  • Sideroblastic anaemia — defective haem synthesis; iron accumulates.

When to discuss with a doctor

Iron-deficiency vs anaemia-of-chronic-disease cannot be distinguished from serum iron alone — the laboratory needs the full iron panel (ferritin + transferrin/TIBC + TSAT) to make the call. Mediora.AI weighs the panel as a whole; do not treat low serum iron in isolation without ferritin to confirm true deficiency.
