Introduction: Transfusion transmissible infections present differences in magnitude and associated factors according to the epidemiological profile of the reference population of each blood bank. Objective: To determine the prevalence of markers of transfusion transmissible infections and associated factors in a Blood Bank Antioquia, 2010-2013. Methods: Cross-Sectional study of prevalence in donors from a blood bank Antioquia in whom inclusion criteria of resolution 901 of 1996 were applied. The source information was secondary and the analyzes were based on the calculation of summary measures, proportions, chi square test, prevalence ratios and evaluation of confusing by binary logistic regression. Results: We included 15 461 donors with a mean age of 36 years. The prevalence of positivity for any marker was 1.18 %, viral infections 0.15 %, Treponema pallidum 1.00 % and T. cruzi 0.02 %. The overall prevalence and of T. pallidum infection was statistically higher in men, elderly, replacement donors and persons with occupation of "services, sports and recreation" and housewives, in the multivariate analysis it showed that these associations did not present confusion. Conclusion: The prevalence of infection was lower compared to previous researches; the subgroups with statistically higher prevalence were men, replacement donors and elderly, this constitute a finding of interest for targeting investigations and health actions.
