血液篩查核酸檢測結(jié)果無效原因分析
[Abstract]:Objective to analyze the causes of ineffective detection results of Cobas S201 nucleic acid detection system in blood screening. Methods from October 2014 to December 2015, the number and type of invalid nucleic acid detection results in our department were counted. The detection time and detection system (A, C) were discussed with the amplification curve, alarm information and detection results. (B and C systems) and reagent lot numbers (batch number 1, batch number 2, batch number 3, batch number 4, batch number 5 and batch number 6) and the occurrence of invalid results, as well as the types of invalidity (internal standard amplification invalid, yin-yang control amplification invalid, Expansion curve exception and marked error code) distribution composition. Results the total inefficiency of nucleic acid detection was 0.21% (47 / 22,284), and the percentage of ineffective type of internal standard amplification was the largest (51.06%), and there was significant difference in inefficiency among the months (P0.05). The results of different detection systems (P0.05) and different batches of reagents (P0.05) were ineffective. The results of C test system (1.59%) and batch number 2 reagent (2.11%) were ineffective. Conclusion there is a certain correlation between the invalid results of nucleic acid detection and different detection systems and different batches of reagents. The inefficiency of monitoring results is helpful to continuously monitor the performance of nucleic acid tests.
