Using selective electrode to measure the concentrations of plasma ionized calcium (ICa) in 222 normal volunteers and 329 patients which included seven kinds of diseases: hyperparathyroidism, overdose of AT10, cancer, hypoparathyroidism, alkalosis, acidosis and hypoalbuminemia was reported. The results demonstrated that this method was rapid, sensitive and reproducible. The concentration of plasma ICa can reflect the calcium metabolism and its disturbance in patients with hyperparathyroidism, hypoparathyroidism, alkalosis, acidosis and hypoalbuminemia precisely, so ICa assay was much better than total calcium measurement.
报道了使用选择性电极测量222名正常志愿者和329名患者的血浆离子钙（ICa）浓度，这些患者包括七种疾病：甲状旁腺功能亢进、AT10过量、癌症、甲状旁腺功能减退、碱中毒、酸中毒和低白蛋白血症。结果表明该方法快速、灵敏且可重复。血浆ICa浓度能准确反映甲状旁腺功能亢进、甲状旁腺功能减退、碱中毒、酸中毒和低白蛋白血症患者的钙代谢及其紊乱情况，因此ICa测定比总钙测量要好得多。
