Ferritin
The body's iron storage protein — also rises during inflammation.
What is it
Ferritin is the primary iron storage protein in the body. It serves as a marker of iron stores but is also an acute-phase reactant that rises during inflammation.
Why it's measured
Ferritin must be interpreted in context: it can be elevated either from iron overload or from active inflammation in published research.
