ABSTRACT
Objective To verify the performances and evaluate the reliability of ACL-TOP700 automatic coagulation analyzer. Methods The analyzer had its precision, accuracy, carryover, linear range, reference interval and etc analyzed and verified according to the requirements of Clinical and Laboratory Standards Institute (CLSI) for PT, APTT, FIB, TT, DDHS, FDP and etc. Results The within-and between-array precision was both lower than 5%, which met the requirements of medical laboratory ISO 15189 requirements;the accuracy satisfied the requirements of external quality assessment by Beijing Center for Clinical Laboratory; linear analysis found high linearity (r≥0.975 or r2>0.95) in FIB, DDHS; the carryovers of FIB and DDHS were-0.34%and-0.10%respectively;more than 90%test results were restrained in the reference interval according to normal distribution principle. Conclusion ACL-TOP700 automatic coagulation analyzer has high performances and reliable results, and thus is worthy promoting clinically.
ABSTRACT
Objective To evaluate the auxiliary diagnostic value of viral load test for samples with indeterminate HIV antibody detection results.Methods Thirty-two samples with indeterminate HIV antibody detection results collected from MSM were used for two viral load tests in Tianjin in 2015.Follow up was conducted for this population to confirm their HIV infection status.Results Virus loads were detected in the 2 viral load tests.In the follow-up survey,the results of HIV antibody test of all the samples were positive.The results of viral load test were completely consistent with those of HIIV antibody confirmation test.Conclusion The viral load test was effective in the auxiliary diagnosis of HIV infection in window phase,which can be used for the samples with indeterminate HIV antibody detection results.
