What is Serum Iron (Serum Iron)?

Serum Iron is measured as part of a iron studies panel. Your serum iron is in a normal range.

What does a high Serum Iron mean?

Elevated serum iron can indicate iron overload, liver disease, or certain anemias (like hemolytic or sideroblastic anemia).

What does a low Serum Iron mean?

Your circulating iron is low. This is often one of the first signs of iron deficiency and usually accompanies low ferritin.

Understand your whole report, not just one number

A single value rarely tells the full story — Serum Iron is best read alongside the rest of your panel. Paste your values or upload your report and get a plain-English explanation of every marker, with the important results flagged.
