Objective To compare and analyze the ELISA and NAT results between first-time donors and repeated donors,and to evaluate the blood safety in different type of blood donors and the necessity of implementing of NAT screening technology.Methods From December 2012 to August 2013,a total of 60,676 blood donors were screened by ELISA and NAT.These donors were divided into first-time donors,second-time donors,and more than 3 times donors.The test Results of ELISA and NAT were analyzed with HBV,HCV,HIV infections by statistics.Results Of 60,676 blood donors,the three types of donors accounted for 60.02%(36,420),15.82%(9,599),and 24.16%(14,657),respectively;the unqualified first-time donors accounted for 1.52% of all first-time donors,while the Ssecond-time donors were 0.77%,and greater than / equal to 3 times donors were 0.52%,respectively.238 donors were NAT positive,accounting for 0.39%;41 discrimination positive donors were ELISA negative,accounting for 0.068%.Conclusion Repeated donors is relatively safer,but there is still residual risk found;NAT can further reduce the risk of transfusion-transmitted deseases.Blood banks shall consolidate and develop the fixed blood donor team,and NAT should be carried out to ensure the blood safety.
