Four studies were conducted, each determining the frequency of hypomagnesemia in patients already found to have one abnormal electrolyte determination. Hypomagnesemia occurred in 42% of patients with hypokalemia, 29% of patients with hypophosphatemia, 27% of patients with hyponatremia, and 22% of patients with hypocalcemia. These observations suggest that detection of either hypokalemia, hypophosphatemia, hyponatremia, or hypocalcemia, all of which are routinely available determinations, should alert the clinician to order serum magnesium determinations because of the frequent association of hypomagnesemia with these electrolyte perturbations. Optimally, levels of serum Mg should be determined on a routine basis because of the frequency of the occurrence of hypomagnesemia in hospitalized patients.
共进行了四项研究，每项研究都确定了已被发现有一种电解质测定异常的患者中低镁血症的发生率。低钾血症患者中低镁血症的发生率为42%，低磷血症患者中为29%，低钠血症患者中为27%，低钙血症患者中为22%。这些观察结果表明，检测低钾血症、低磷血症、低钠血症或低钙血症（所有这些都是常规可进行的测定），应提醒临床医生开具血清镁测定单，因为低镁血症与这些电解质紊乱经常相关。理想情况下，由于住院患者中低镁血症的发生率较高，应定期测定血清镁水平。
