RESUMO

Objective To verify the feasibility of Chlamydia trachomatis(CT),Neisseria gonorrhoeae(NG),Ureaplasma urealyticum(UU)detection by automatic nucleic acid extraction workstation(MagX).Methods The test samples of CT (159),NG(128)and UU(144)were collected.The samples were extracted of nucleic acid two methods:manual extraction, which entailed manually preparing PCR reaction system and MagX automatic nucleic acid extraction workstation,which au-tomatically prepared the reaction system.The two parts of nucleic acids proceeded to the Simultaneous Amplification and Testing(SAT).The result of manual extraction was set as the golden standard and the Kappa consistency analysis was con-ducted.Meanwhile,the sensitivity,specificity,accuracy and carry pollution experiments of MagX were verified.Results The sensitivity of MagX automatic nucleic acids extraction workstation were 92.59%(CT),100.00%(NG)and 93.33%(UU).The specificity were 98.48%(CT),98.18%(NG)and 95.24%(UU).The accuracy were 97.48%(CT),98.44%(NG)and 94.44%(UU).The results of kappa consistency analysis were greater than 0.8(CT:Kappa=0.910 6,NG:Kap-pa=0.938 3,UU:Kappa=0.885 6).MagX detected the precision of CT,NG and UU:Coefficient of Variation(CV)<5%. There was no pollution phenomenon.Conclusion MagX automatic nucleic acids extraction workstation could be used to test three kinds of sexually transmitted pathogen in clinical settings.
