Iron Studies
The iron studies panel measures the body's iron stores and transport capacity. It typically includes ferritin (iron stores), serum iron, total iron-binding capacity (TIBC), and transferrin saturation. These markers are used together to characterise iron status across the spectrum from deficiency to overload.

Frequently Asked Questions
Why are ferritin, serum iron, TIBC, and transferrin saturation grouped together?
They describe complementary parts of iron physiology: stored iron, circulating iron, binding capacity, and the proportion of transport sites occupied. The combined pattern is usually more informative than any single marker alone.
Why can iron studies be harder to interpret than many chemistry tests?
Several of these markers shift with inflammation, supplementation, time of day, or liver protein synthesis. Looking across the full iron panel helps separate low iron stores from altered transport dynamics.
