INFLAMMATION
Ferritin
Also known as Ferritin
What it is
Ferritin is the body's iron storage protein. It also rises with inflammation as an acute-phase reactant.
Why it matters
Ferritin is a dual-purpose marker: iron status and inflammation. Interpretation requires knowing both.
Range GPLX watches for
GPLX watches for ferritin in the mid-range of the lab reference in symptomatic patients. Very low ferritin suggests iron deficiency; very high can suggest inflammation or iron overload.
This educational range is not a personal diagnostic threshold. Your physician interprets your result in context of your full biomarker panel, medications, symptoms, and history.
What abnormal values can suggest
If low
A low ferritin value strongly suggests iron deficiency, even before anemia develops.
If high
A high ferritin value can suggest inflammation, liver disease, alcohol use, iron overload (hemochromatosis), or metabolic dysfunction.
