Estimation of ferrioxamine in jaundiced urine.

A simple modification to Fielding and Brunström's method for the estimation of ferri-oxamine is described for use with jaundiced urine. Manufactured ferrioxamine HC1 may be slightly impure, and when used for standard purposes should be rendered anhydrous and checked for iron content. Standard ferrioxamine solutions suitable for calibrating Fielding and Brunström's method may be prepared by adding standard quantities of ferric iron to excess desferrioxamine.
