Intended Use
For the quantitative determination of magnesium in serum using the Tokyo Boeki Medisys Inc. Biolis 24i 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.
