血钙与高钙血症血液中血清(或血浆)钙浓度约为10mg/dl,保持于比较窄的范围内的恒定.其中约50%以游离的钙离子形式存在.剩余的大部分主要是与血清清蛋白相结合,一部分与柠檬酸、磷酸等相互作用而存在.具有生物学作用,并保持恒定的是钙离子部分,严格地说,高钙血症应该是高钙离子血症.用表1的方法可校正由于血清清蛋白浓度的变化引起钙离子浓度变化而伴有的血清钙浓度变化.表1 与血清蛋白变化相对应的血清钙浓度校正法
Serum calcium and hypercalcemia Blood serum (or plasma) calcium concentration of about 10mg / dl, to maintain a relatively narrow range of constant, of which about 50% of the free calcium ion form the majority of the remaining mainly Combined with serum albumin, part of the interaction with citric acid, phosphoric acid, etc. There is a biological role, and maintain a constant part of the calcium ion, strictly speaking, hypercalcemia should be hypercalciuria. The method in Table 1 corrects for changes in the serum calcium concentration associated with a change in the concentration of calcium ion due to a change in serum albumin concentration.Table 1 Serum calcium concentration corrections corresponding to changes in serum proteins
