血液标本放置方式对生化指标检测结果的影响

目的 对采用不同放置时间对血液中的多项生化指标进行检测的作用进行研究分析.方法 抽取2008年6月至2011年6月来胜利石油管理局河口医院就诊的90例接受血液检验的患者,将其分为A、B两组,平均每组45例.A组患者的血液标本即刻检测;B组患者的血液标本在保存2d后进行检测.对两组患者的血液标本检测的丙氨酸氨基转移酶(ALT)、总胆红素(TBIL)、梅毒螺旋体(TP)、血尿素氮(BUN)、血清肌酐(CR)、尿酸(UA)、血糖(GLU)、清蛋白(ALB)水平进行比较分析.结果 经过仔细研究后发现,B组患者的ALT、TBIL、BUN水平明显低于A组患者,差异有统计学意义(P＜0.05);该组患者的其他5项指标略低于A组患者,差异无统计学意义(P＞0.05).结论 接受血液检测患者的血液标本在放置一段时间后,会导致ALT、BUN、TBIL水平明显下降,导致无法检测出准确值,但对TP、CR、UA、GLU、ALB等5项指标不会造成特别大的影响,基本可以测得准确值.

Analysis on influence of blood placement modes on biochemical indexes detection

Objective To investigate the influence of different placement time on blood biochemical indexes de- tection. Methods 90 patients receiving blood tests in our hospital from June 2008 to June 2011 were selected and di- vided into group A and B,45 cases in each group. The blood samples from the group A were immediately detected, but the blood samples from the group B were detected after placing for 2d. The detection results of ALT,TBIL,TP, BUN,CR,UA,GLU, ALB levels were compared between the two groups. Results After careful investigation, we found that the levels of ALT,TBIL and BUN in the group B were significantly lower than those in the group A with statistical difference between them（P〈0.05）. The other five indexes in the group B were slightly lower than those in the group A without statistical differences between the two groups （P〉0.05）. Conclusion After placing the blood specimens for a period of time, the detection levels of ALT, BUN and TBIL could be significantly decreased, which leads that the exact values are unable to be detect,but does not cause a great influence on the other five indexes TP, CR,UA,GLU and ALB,and their accurate values could be detected.
