摘要:

目的 探讨内源性干扰物质血红蛋白(Hb)、胆红素、乳糜微粒和外源性干扰物质羟苯磺酸钙对干化学(Vitros 5600系统)和湿化学(cobas c501系统、迈克-7180系统)检测系统常规生化项目检测的影响。方法 根据美国临床实验室标准化协会(CLSI)EP7-A2文件要求,采用高、低2个水平的血清或血浆基础样本,与干扰物质配制成不同浓度梯度的Hb、胆红素F、乳糜和羟苯磺酸钙干扰样本,模拟轻、中、重度干扰。分别采用Vitros 5600系统、cobas c501系统和迈克-7180系统检测干扰样本,计算干扰样本与基础对照样本检测结果的相对偏移和绝对偏移。结果 在Hb干扰试验中,Vitros 5600系统13个项目中有9个受到不同程度的干扰,cobas c501系统13个项目中10个受干扰,迈克-7180系统11个项目中有8个受干扰。在胆红素干扰试验中,Vitros 5600系统11个项目中有3个受干扰,cobas c501系统11个项目中有5个受干扰,迈克-7180系统9个项目中有2个受干扰。在乳糜干扰试验中,Vitros 5600系统12个项目中有2个受干扰,cobas c501系统12个项目中有4个受干扰,迈克-7180系统10个项目中有4个受干扰。羟苯磺酸钙对3种检测系统的肌酐(Cr)项目均有明显干扰,但Vitros 5600系统的受干扰程度要小于其他2种系统。结论 在常规生化项目的检测中,不同的检测系统均会受内源性和外源性干扰物质的影响,但干化学检测系统的抗干扰能力整体强于湿化学检测系统。

Abstract:

Objective To investigate the effects of endogenous interfering substances [hemoglobin(Hb),bilirubin,chylomicrons] and exogenous interfering substance(calcium dobesilate) on the routine biochemical tests of 3 determination systems [Vitros 5600 system(dry chemistry),cobas c501 system(liquid chemistry),Maccura-7180 system(liquid chemistry)]. Methods According to the requirements of EP7-A2 document of the Clinical and Laboratory Standards Insititution(CLSI),serum or plasma basic control samples with high and low levels were used to formulate Hb,bilirubin F,chylomicrons and calcium dobesilate interference samples with different concentration gradients to simulate light,moderate and severe interference. Vitros 5600 system,cobas c501 system and Maccura-7180 system were determined,and the relative and absolute deviation of the determination results from the basic control samples were calculated. Results In the Hb interference test,9 of 13 items of Vitros 5600 system were interfered;10 of 13 items of cobas c501 system were interfered;8 of 11 items of Maccura-7180 system were interfered. In the bilirubin interference test,3 of 11 items were interfered in Vitros 5600 system,5 of 11 items in cobas c501 system,and 2 of 9 items in Maccura-7180 system. In the chylomicrons interference test,2 of 12 items were interfered in Vitros 5600 system,4 of 12 items in cobas c501 system,and 4 of 10 items in Maccura-7180 system. Calcium dobesilate interfered with creatinine(Cr) items of the 3 determination systems,but the degree of interference of Vitros 5600 system was less than that of the other 2 systems. Conclusions In the routine biochemical tests,different determination systems are affected by endogenous and exogenous interfering substances. The anti-interference ability of dry chemistry determination system is better than those of liquid chemistry determination systems.
