Objective To explore and establish the corrective procedure to deal with the carry-over of BECKMAN DXC800 automatic biochemistry analyzer. Methods To reduce the carry-over between serum total protein (TP) and serum Cu2+, the carry-over test of sample probes and muddlers, cuvettes, reagent probes were carried out in series, to find out pollution source,then corresponding treatment and verification were made. Results The carry-over of sample probes and muddlers,cuvettes,reagent probes were 0. 81%, —0. 41%,186. 5%, respectively. So the pollution source was reagent probe. The carry-over of reagent probe was 0. 81% after treatment which met the quality aim of our laboratory. Conclusion The corrective measures to carry-over of BECKMAN DXC8000 biochemical analysis are feasible and effective.%目的 探讨并建立BECKMAN DXC800自动生化分析仪携带污染的纠正措施.方法 以血清总蛋白与血清铜离子项目间的携带污染为例,通过初步分析样品针及搅拌棒携带污染、比色杯携带污染、试剂针携带污染的状况,检出污染源,并作出相应处理后进行有效性验证.结果 样品针及搅拌棒、比色杯、试剂针的携带污染率分别为0.81％、-0.41％、186.5％,所以试剂针的携带污染为污染源,对其处理后的携带污染率为0.81％,满足实验室要求.结论 建立的BECKMAN DXC800生化仪分析携带污染的纠正措施可行且有效.
