title: [The clinical significance of measuring plasma ionized calcium concentration].
abstract: 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.
