竹签接触血清样品时间对钾离子浓度的影响

为探讨竹签接触血清样品时间对钾离子浓度影响的程度,采用离子选择电极法分别对竹签在血清中浸泡不同时间的样品钾离子浓度进行测定,并以配对t检验对不同浸泡时间的血清钾离子浓度进行对比.结果表明:在一定时间范围内,钾离子浓度随竹签浸泡时间的延长而呈逐渐增高趋势,其差异具有统计学意义(P<0.01).由此提示竹签含钾是导致与其接触的样品钾离子浓度增高的主要因素.

The Effect of Bamboo Stick Contacting Time with Serum Sample on Potassium Ion Concentration

To explore the effect of bamboo stick contacting time with serum sample on serum potassium ion concentration,we have systematically measured serum potassium ion concentration of bamboo stick contacting with serum sample at different times using Ion selective electrode method and analyzed their potassium ion concentrations using matching t test.Results show that potassium ion concentration has a gradual higher with the extension of bamboo stick immersion times in a certain time and that statistical differences among serum potassium ion concentration at difference times is significant(P<0.01).It seems that bamboo stick contacting potassium ion may be a major reason resulting in making serum potassium ion concentration of serum sample with which bamboo stick contacted higher.
