Magnesium and phosphorus normally are present in very low serum concentrations and usually are not included in common serum electrolyte laboratory studies. Though their normal serum concentrations are relatively low, both of these ionized minerals are necessary for many critical physiologic functions, and decreases in normal serum levels can have serious deleterious effects. Some of these effects, especially in myocardial tissues, may lead to permanent tissue damage. Hospitalized patients at greatest risk for developing hypomagnesemia or hypophosphatemia are trauma victims; individuals with poorly controlled diabetes mellitus, renal impairment, parathyroid dysfunction, or chronic alcoholism; and individuals who have been treated with antineoplastic agents.
镁和磷通常在血清中的浓度非常低，一般不包括在常见的血清电解质实验室检查中。尽管它们的正常血清浓度相对较低，但这两种离子化矿物质对许多关键生理功能都是必需的，正常血清水平的降低可能会产生严重的有害影响。其中一些影响，尤其是在心肌组织中，可能会导致永久性组织损伤。发生低镁血症或低磷血症风险最高的住院患者是创伤受害者；糖尿病控制不佳、肾功能损害、甲状旁腺功能障碍或慢性酒精中毒患者；以及接受过抗肿瘤药物治疗的患者。
