摘　　要：目的 比较不同仪器检测模拟急诊生化标本的效率。方法 采用A、B、C 3台生化分析仪分别检测单份标本和批量标本(40份)常规化学单一项目、全套项目,记录所需时间。按照不同的项目组合顺序(顺序1、顺序2)检测20份标本,记录所需时间。使用不同的仪器组合(Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ)检测10份标本常规化学与心肌标志物组合项目,分别按照分管和不分管、先测常规化学项目和先测心肌标志物项目进行检测,记录所需时间。分别在开启和关闭血清指数检测功能的状态下采用仪器A、B、C检测40份血清标本(含干扰物质的溶血、黄疸、脂血标本各5份),比较检测不同状态标本所需时间。随机选取4名检测人员目测判断40份血清标本状态,记录所用时间和结果,计算目测结果的符合率。对3台生化分析仪进行每日维护保养,记录所用时间。结果 单份标本在仪器A、B、C上检测葡萄糖项目所需时间分别为6、16、12 min,检测全套常规化学项目所需时间分别为8、18、14 min。批量标本在仪器A、B、C上检测葡萄糖项目所需时间分别为12、19、15 min;检测全套常规化学项目所需时间分别为103、112、72 min。按照不同常规化学项目顺序检测20份标本,仪器A、C用时不变,仪器B顺序2较顺序1用时增加1 min。10份标本常规化学和心肌标志物组合项目检测,组合Ⅰ用时34 min,不分管仪器组合Ⅱ、Ⅲ、Ⅳ、Ⅴ先测常规化学项目用时分别为67、60、92、80 min,先测心肌标志物项目用时分别为69、53、72、71 min;分管检测用时分别为58、48、69、69 min。仪器A、B、C开启和关闭血清指数检测功能检测40份标本全套常规化学项目所需时间相同。4名检测人员目测法判断40份血清标本状态平均用时122 s,对溶血、黄疸、脂血标本判断结果平均符合率分别为100%、48%和76%。A、B、C 3台生化分析仪每日维护保养时间分别为13、21、35 Objective To compare the testing efficiency of simulated emergency biochemical samples among different instruments. Methods Single analyte and full-set analytes for single sample and a batch of samples(40 samples) were tested with 3 different instruments(A,B,C),respectively. The testing times of different instruments were recorded. Totally,20 samples were tested in different sequences(sequence 1 and sequence 2),and the testing time were recorded. Totally,5 instrument combinations(Ⅰ,Ⅱ,Ⅲ,Ⅳ,Ⅴ) were used to test biochemical analytes and cardiac markers for 10 samples. The combinations were determined according to various processes,and the testing times were recorded. Both split sample and unsplit sample were determined on the combinations. The samples were determined in the process of biochemical analytes first or cardiac markers first. A total of 40 samples,containing 5 hemolytic,5 icteric and 5 lipemic samples,were collected,and the 40 samples were also inspected by 4 technicians by visual. The testing time and results were recorded,and the coincidence rates of visual results were calculated. Daily maintenance for the 3 instruments was performed,and the testing time was recorded. Results It took 6,16 and 12 min to test glucose for single sample for instrument A,B and C,respectively,and 8,18 and 14 min to test full-set analytes for the above instruments,respectively. It took 12,19 and 15 min to test glucose for a batch of samples for instrument A,B and C,respectively,and 103,112 and 72 min to test full-set analytes. It took the same time to test the same analytes for 10 samples in different sequences for instrument A and C,while it took 1 more min in sequence 2 than in sequence 1 on instrument B. When 10 samples were tested for biochemical analytes and cardiac markers,it took combination Ⅰ 34 min. It took combination Ⅱ,Ⅲ,Ⅳ and Ⅴ 67,60,92 and 80 min,respectively,when testing biochemical analytes firstly. It took 69,53,72 and 71 min respectively when testing cardiac markers firstly. It took 58,48,6
