Intended Use

The Sekisui Magnesium Assay is for the quantitative determination of magnesium in human serum and plasma (Lithium Heparin) on automated chemistry analyzers. Magnesium measurements are used in the diagnosis and treatment of hypomagnesemia (abnormally low levels of magnesium) and hypermagnesemia (abnormally high levels of magnesium). This device is intended for professional use and IN VITRO diagnostic use only.

Device Description

The Sekisui Magnesium assay kit consists of the following: Magnesium Reagent: A solution containing buffer (pH 11.2 at 25°C), 0.14 mmol/L xylidy/ blue-1, 0.1 mmol/L EGTÅ, and a surfactant.
