A variety of methods have been reported for the quantitative analysis of magnesium in serum and other biological fluids. The methods may be classified into the following groups: magnesium ammonium phosphate; 8-hydroxyquinoline; titan yellow; dihydroxyazobenzene using fluorimetry; Schwarzenbach ethylenediaminetetraacetic acid;
