Study on sero-indexes among 2690 qualified blood donors

  Objective   To understand infectious status of other common pathogens among donors and to provide scientific basis for increasing blood quality.

  Methods   HAV-IgM, anti-HBc, HBeAg, anti-HBe were tested by enzyme linked immunosorbent assay(ELISA); Anti-EBV-IgA, anti-HCMV and anti-toxoplasm were tested by enzyme immunoassay (EIA)and indirect blood agglutination, respectively.

  Results   In the first stage of the study, the percentage of donors that had at least a positive index among HAV, HBeAg, anti-HBe, anti-HBc, anti-HCMV, anti-EBV, anti-toxoplasm(7 indexes)was 30.7%.In the second stage of the study, the percentage of donors thathad at least a positive index among HBeAg, anti-HBe, anti-HBc, anti-HCMV, anti-EBV(5 indexes)was 43.2%.

  Conclusion   Besides testing routine indexes, it was necessary that HBeAg, anti-HBc, anti-HCMV, anti-EBV and anti-toxoplasm be tested among donors, which can lower the incidene of transfusion transmitted diseases.
