Abstract:
Objective To analyze the screening and confirmation test results of human immunodeficiency virus (HIV) antibody during 2009-2015 to provide the basis for the recruiting strategies in recruiting blood donors among the low risk population and blood donor′s returning to the team .Methods The blood samples of voluntary blood donors were detected the HIV antibody by the ELISA method ,with the reagents provided by 2 different manufacturers .The samples of HIV antibody positive or suspected sam‐ples were submitted to the Shenzhen Municipal Center for Disease Control and Prevention CDC for conducting the Western blot confirmation .The confirmation results of blood samples during 2009 -2015 were statistically analyzed .Results There were 197 766 blood samples from 2009 to 2015 .The overall infection rates of HIV were 1 .3 ,4 .7 ,5 .6 ,5 .4 ,5 .3 ,4 .6 ,7 .3/one hundred thousand respectively ,the average infection rate was 0 .004 9% (4 .9/one hundred thousand) ,the average confirmed positive rate was 22 .1% ,the false positive rate was 77 .9% .Among the blood donors of confirmed positive HIV antibody ,the donors aged 18-30 years old accounted for 67 .7% .Conclusion It is important for the recruitment work before the blood donation .Aiming at the blood donors of workers from outside and relative low cultural level ,especially the blood donors of high risk behavior ,the small card mode could be adopted to guide them to the disease control center to conduct the professional consultation and detection ,which can increase the blood transfusion safety coefficient and also prevents the spread of HIV/AIDS .Aiming at the false positive blood do‐nors ,the works of follow up ,tracking monitoring and return to the blood donation team should be done well for reducing the run a‐way of blood donors .Selecting more sensitive reagents and more sensitive method for the amplification of virus nucleic acid can shorten the infection risk of the window period as far as possible for ensuring the safety of blood transfusion .
