Colorimetric measurement of serum and urine magnesium with the Cobas Mira Analyzer

Conclusion The major advantage of the xylidyl blue-1 method over kits using the calmagite reagent is the stability of the alkaline reagent mixture ready for use [5]. Furthermore, the kit benefits from fewer interferences than the calmagite procedure [3]. The kit performed well in terms of precision, sensitivity and linearity and the results correlate excellently with those by atomic absorption spectrophotometry.
