Allantoin in human urine quantified by ultra-performance liquid chromatography-tandem mass spectrometry.

Journal Article

Uric acid is a potent antioxidant and scavenger of singlet oxygen and other radicals in humans. Allantoin, the predominant product of free radical-induced oxidation of uric acid, is efficiently excreted in the urine and has potential as a biomarker of oxidative stress. We developed a rapid and specific assay for urinary allantoin using ultra-performance liquid chromatography-tandem mass spectrometry suitable for high-throughput clinical studies. The method required minimal sample preparation and was accurate (mean error=6%), precise (intra- and interday imprecision <8%), and sensitive (limit of detection=0.06pmol). Allantoin levels measured in control samples were comparable to literature values.
