	abstract = {<p>The ferrozine assay is a widely used colorimetric method for determining soluble iron concentrations. We provide evidence for a heretofore unrecognized interference of ferric ions (Fe(3+)) on ferrous iron (Fe(2+)) measurements performed in the dark. Fe(3+) concentrations affected the absorbance measurements, which linearly increased with incubation time.</p>},
