Methods: his is a cross-sectional study (descriptive and analytical) developed from the collection of medical records of blood donors treated from January 2011 to December 2015 in the hepatitis clinic of Núcleo de Medicina Tropical. Results: Of the total of 1932 records analyzed, 1217 donors considered unfit had the serological retestation in Núcleo de Medicina Tropical. Retention showed 556 cases (76.1%) total Anti-HBc reagents, of which 408 (55.8%) had previous contact immunity; 71 (9.7%) were reagents for HBsAg and 454 (63.3%) reagent for Anti-HBs. There was no significant difference in HBsAg positive for mean age (p = 0.0642) and for gender (p = 0.2108). Conclusion: The high infectivity of the virus and the positive cases for the disease still constitute a serious public health problem because it is a silent disease. It is important to highlight the importance of the complementary care services referenced to guarantee support to donors considered unfit by the hemocentres, since after the discard it is common for patients to find difficulty in care in the Brazilian health system.
