A colorimetric procedure is described for the determination of serum iron and TIBC, utilizing
the action of the iron on the oxidation reaction of 4-aminophenazone with H 2 O 2. The
chromogen oxidized has maximum absorption at 540 nm. The method is interesting
because it has important advantages over other methods: no deproteinization is needed,
microsamples are used, it is simple, gives adequate precision, and the results correlate well
with those obtained with the standard bathophenanthroline method.
