Intended Use

For the quantitative determination of magnesium in serum using the Mindray BS-480 analyzer. For in vitro diagnostic use only.


Serum magnesium ions react with Xylidyl Blue in an alkaline solution to produce a red complex that is measured spectrophotometrically. The intensity of color produced is directly proportional to magnesium concentration. Calcium interference is virtually eliminated by use of EGTA and a surfactant system is included to remove protein interference.
