镁代谢失常日益受到重视,但镁的测定在国内实验室仍较少开展,镁正常值的测定也很少报道,国外报道虽然较多,但尚无公认标准。在测定方法方面,原子吸收分光光度法虽较佳,但设备贵,不能普及,而化学法又有灵敏度不够或可靠性较差的缺点。针 Magnesium metabolic disorders are increasingly valued, but the determination of magnesium in the domestic laboratory is still less developed, the determination of magnesium is rarely reported, although there are many foreign reports, but there is no recognized standard. In the determination of methods, atomic absorption spectrophotometry is better, but expensive equipment, can not be universal, and chemical sensitivity and lack of reliability or poor shortcomings. needle
