MAGNESIUM - XYLIDYL BLUE, 2 x 100 mL

PRINCIPLE

In an alkaline medium, the magnesium ions of the sample will produce a coloured complex with Xylidyl blue. Colour intensity is directly proportional to the magnesium ions concentration present in the sample. Ehylene glycol-bis(2-aminoethylether)-N,N,N?,N
tetraacetic acid (EGTA) performs as a chelating agent.

DIAGNOSTIC USE

Magnesium is found in the bone and in the cells of tissues and organs. Magnesium is necessary for nearly all biochemical processes in the body. It helps to maintain normal muscle and nerve function, it keeps the bone strength, it controls heartbeat and it helps to regulate blood pressure. Magnesium also controls the levels of sugar in the blood and it helps strengthen the bodys immune system.

Main causes of magnesium defi ciency are intestinal malabsorption, pancreatitis and hypoparathyroidism. High concentrations are found in dehydration, renal insufficiency, Addison disease, hypothyroidism and ingestion of anti-acids.

Single test result could not be used to make a clinical diagnosis. It should integrate clinical and laboratory data.
