Narrative review outlines four stable iron isotope techniques for evaluating human ferrokinetics, highlighting their utility in designing targeted interventions against iron deficiency anemia.

Key Points

To review four stable iron isotope techniques used to quantify human iron absorption, systemic utilization, and long-term ferrokinetics.
Evaluated four stable isotopic tracer modalities: fecal recovery, plasma isotope appearance, erythrocyte iron incorporation, and iron isotope dilution.
Assessed technical parameters across modalities, including oral versus intravenous tracer administration, acute plasma kinetic curves, 14-day red blood cell tracer incorporation, and long-term whole-body isotopic equilibration.
Fecal monitoring directly isolates unabsorbed oral tracer from endogenous intestinal cell loss, while plasma appearance curves capture acute absorption rates, peak concentrations, and area under the curve.
Dual-tracer erythrocyte incorporation accurately distinguishes intestinal absorption from bone marrow utilization, and whole-body isotope dilution allows long-term quantification of cumulative iron gains and losses.
