A simple and rapid method for the determination of ferrioxamine iron in urine, in which the colour reagent is added directly to centrifuged urine after reduction with dithionite, has been critically evaluated and compared with a method of iron determination after wet ashing. The coefficient of variation of both methods was less than 5%. A very high correlation was found between the values obtained with the two methods, but the simple method gave consistently lower values, averaging about 85% of those by the wet ashing method. Iron present in the urine sediment or bound in a soluble form which is not split off by dithionite will not be measured with the simple method. Despite its lower values the simple method gives uniform and reliable results, and is considered suitable for the performance of the desferrioxamine test.
一种用于测定尿中铁胺铁的简单快速方法，即在连二亚硫酸盐还原后将显色试剂直接加入离心后的尿液中，该方法已得到严格评估，并与湿灰化后铁的测定方法进行了比较。两种方法的变异系数均小于5%。发现两种方法所得值之间具有非常高的相关性，但简单方法所得值始终较低，平均约为湿灰化法所得值的85%。尿沉渣中存在的铁或以连二亚硫酸盐不能分解的可溶形式结合的铁，用简单方法无法测定。尽管其值较低，但简单方法能给出一致且可靠的结果，被认为适用于去铁胺试验。
