The effect of prior transfusion history on blood donor anti-hepatitis C virus antibody.
In Japan, the major transfusion-associated disease is non-A, non-B hepatitis. We studied the relationship between transfusion history and blood donor antibodies to hepatitis C virus (HCV). The positive rate of antibodies to the HCV nonstructural protein (c100-3) depended on age and the time elapsed since transfusion. The anti-c100-3 ratio for subjects with transfusions made prior to 20 years ago was high. One quarter century ago, a change occurred in national blood policy from paid to non-paid voluntary donations. We also have studied the anti-HCV positive rate among donors with prior transfusion using a second generation HCV test kit which includes anti-HCV core antibody detection. The anti-HCV positive rate for the second generation test was higher than that for the anti-c100-3 test. Introduction of the second generation test is therefore more useful in screening than the anti-c100-3 test for blood programs.
