Introduction: Hemotherapy consists of therapeutic treatment using blood transfusion. Because of the vast amount of bloodborne infectious diseases, highly sensitive laboratory tests must be conducted to minimize the transfusion risks for donors and recipients. Thus, the present study aimed to evaluate the prevalence of hepatitis B and C serological markers in samples from a blood bank in Porto Alegre, southern Brazil, as well as the correlation between serology and nucleic acid amplification testing (NAT). Methods: A quantitative, descriptive, retrospective study was conducted to analyze blood donor information obtained from a blood bank database in Porto Alegre, southern Brazil, concerning 2017 and 2018. Serology and NAT results for hepatitis B and C were examined. Results: Of 17,181 blood donations, the total number of serologically reactive samples was 162 (0.94%) for anti-HBc, 20 (0.12%) for HbsAg, and 62 (0.36%) for anti-HCV. Only 4 (0.02%) samples were simultaneously reactive for anti-HBc and HbsAg, being also positive in NAT. The number of samples reactive to hepatitis C in NAT was 18 (0.10%). Conclusions: Biotechnological evolution has contributed to biosafety in blood transfusions. Considering that NAT is relatively recent in blood banks, further studies using different time periods are suggested for yielding satisfactory results for transfusion safety and elucidating the combination of serological testing and NAT at blood banks.
