Ferritin

Ferritin is the primary intracellular protein that stores iron and releases it in a controlled fashion. In a COVID-19 profile, Ferritin serves as an Acute Phase Reactant. It is a marker of the 'Cytokine Storm' and hyperinflammation. High levels in COVID-19 patients correlate with increased disease severity, lung injury, and poor prognosis, independent of iron stores.

Why Context Matters
Since Ferritin rises during any inflammation, infection, or liver disease, a high level does not necessarily mean iron overload (hemochromatosis). Conversely, a 'normal' ferritin in an inflammatory state could hide an underlying iron deficiency.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
