摘要
目的探讨动脉血浆、静脉血浆、动脉血清、静脉血清之间电解质、葡萄糖结果的差异及其原因。方法采集54例患者动静脉抗凝血、动静脉凝集血各1管,分离出相应的血浆和血清,用强生VITROS 5600自动干式生化分析仪对K^+、Na^+、Cl^-、血糖的浓度进行测定,并应用统计学方法对检测结果进行比较分析。结果当标本类型为血清时,动脉血与静脉血之间Na^+、Cl^-、血糖和血清K^+浓度的测定值差异有统计学意义(P<0.05);当标本类型为血浆时,动脉血与静脉血之间Na^+、Cl^-、血糖浓度的测定值差异有统计学意义(P<0.05),但K^+浓度差异无统计学意义(P>0.05)。另外,动脉的血浆和血清之间血糖和血K^+的测定值差异有统计学意义(P<0.05),而Na^+、Cl^-测定值的差异无统计学意义(P>0.05);同样的,静脉的血浆和血清之间血糖和血K^+的测定值差异有统计学意义(P<0.05),而Na^+、Cl^-测定值的差异无统计学意义(P>0.05)。结论同一检测系统检测电解质、葡萄糖,动脉血浆、静脉血浆、动脉血清、静脉血清之间测定值存在一定差异,临床上应注意区别对待不同类型标本的测定值,建立、选择合适的参考范围。
Objective To investigate the difference in detection results of electrolytes and glucose among arterial blood plasma , venous blood plasma ,arterial blood serum and venous blood serum .Methods Arterial and venous anticoagulation blood and coagu‐lation blood were collected from 54 patients at the same time ,1 tube for each blood sample .The corresponding plasma and serum were isolated .The levels of K＋ ,Na＋ ,Cl-and glucose（GLU） were determined by using the Johnson VITROS 5600 automatic dry biochemical analyzer .The detection results were performed the comparative analysis by using the statistical method .Results When the sample was serum ,the concentrations of Na＋ ,Cl- ,GLU and serum K＋ had statistically significant difference between arterial and venous blood（P〈0 .05） ,when the sample was plasma ,the concentrations of Na＋ ,Cl- and GLU had statistically significance between arterial and venous blood（P〈0 .05）;but the K＋ concentration had no statistically significant difference between serum and plasma（P〉0 .05） .In addition ,the GLU and K＋ detection results had statistical difference between arterial serum and plasma（P〈0 .05） ,while the Na＋ and Cl- detection results had no statistically significant difference（P〉0 .05）;similarly ,the GLU and K＋ de‐tection results had statistical difference between venous plasma and serum （P〈0 .05） ,while the Na＋ and Cl- detection results had no statistical difference（P〉0 .05） .Conclusion Some differences in the detection results of electrolytes and glucose exist among ar‐terial plasma ,venous plasma ,arterial serum and venous serum ,clinic should pay attention to make a difference among different types of sample and establish the suitable reference ranges .have certainly difference in different types of specimens even detected by the same system .So we recommend that appropriate reference range is necessary for various kinds of specimens .
