Fischer's method for rapid detection of acute iron toxicity is modified to suit pediatric cases. TPTZ (2,4,6-tripyridyl-s-triazine) is the chromogen of choice since in a small volume of serum slight to moderate hemolysis can cause a false positive result bathophenanthroline. Ordinary labware is amenable to this simplified procedure.
