Human blood (1%) and ribavirin were selected to verify the anti-interference ability, and the weak positive samples were still weak positive after repeated determination for three times. The cross-reaction was verified by Haemophilus influenzae and Klebsiella pneumoniae, and it was repeated for 3 times, all of which were negative. Repeatability verification: two people, 20 days and two batches of kits were used to detect the biological negative and weakly positive quality control products of Kunlai, and the coincidence rate was 100%.
Conclusion: The coincidence rate, detection limit, cross reaction, anti-interference ability, repeatability and other performance indexes of COVID-19 nucleic acid rapid detection analyzer UC0 108 in detecting novel coronavirus all meet the performance indexes declared by manufacturers, and can meet the requirements of rapid detection of nucleic acids in COVID-19.
