Several studies have demonstrated association of blood group systems with different pathologies. Therefore, this work aimed to investigate the association between HCV and blood groups ABO and Rh blood donors Hemopa Foundation from 2000 to 2010. Between January 2000 and December 2010 were analyzed 565,614 samples from individuals who donated blood in Hemopa, and 1064 showed these test reagent for HCV serologic survey, 1246 inconclusive and 563.304 negative. However, this study included only those blood donors who did not have any kind of co-infection to any other pathology researched, naturally Pará and brown skin. After the selection of these criteria led to a sample size of 838 (0.15%) seropositive in 1181 (0.21%) inconclusive and 551,991 (99.64%) seronegative for a total of 554.010 blood donors. For serological diagnosis of hepatitis C were used serological test ELISA (enzyme immunoassay) 4th generation for detection of specific anti-HCV in the serum of donors and the samples positive by serology (ELISA) was carried out extraction of viral RNA. The ABO and Rh blood groups were determined by the research of antigens A and / or B, anti-A and / or anti-B antibodies and Rh (D) antigens in the blood sample from the individual. Over the years we found that the seroprevalence of HCV-specific antibodies in blood donors has undergone reduction, ranging from 132 to 38 cases reactive serum. Most donors were between the age group 30-49 years (57.64%), belonging to the predominantly male 74.5% (624/838) and coming from Belém 72.5% (607/838). When the distribution of the phenotypes of the ABO and Rh blood groups systems between the donor reactive serum and non-reactive to HCV, it was found that no significant variation in the frequency of these phenotypes donor reagents and reactants in the non-HCV-specific antibodies. Donor blood PCR results showed that when compared to Rh and ABO blood groups of patients there was no association between them.
