Résumé
Objective To investigate the situation of ALT-single-unqualified blood donors and the ALT test when they donated again.Methods There were 3 784 cases of ALT-single-unqualified blood donors from March 2009 to February 2010 enrolled in the study.Investigations were carried out to know the previous situation of blood donation.A 3-year tracking survey on those people was carried out,and the data was recorded and analyzed.Results The ALT-single-unqualified blood donors who participated in blood donation for the first time accounted for 58.14% (2 201/3 748).The 3-year follow-up showed that the returned blood donors accounted for 33.62% (1 272/3 784);1-year return accounted for 46.62%(593/1 272)which was the most;ALT-qualified donors accounted for 65.72%(836/1 272)of the retured donors.with the increase of the times of blood donation,the qualified rate of blood ALT increased.Conclusion More than half of the ALT-single-unqualified blood donors returned.There was a large proportion of returning donors participated in blood donation more than onece,and the qualification rate of ALT increased with the increase of do-nation times.In order to reduce the unqualified rate of ALT test,we should strengthen the propaganda and fixed blood donation team construction.
