Objective: To assess the reproducibility and validity of the scale of perceived quality in donors from a blood bank in the city of Medellín. Methods: Psychometric evaluation in 301 blood donors through internal consistency with Cronbach’s alpha and discrimination index. Content validity of the polls and factorial structure were evaluated by means of exploratory factor analysis. Results: Cronbach’s alpha was 0.86. For the expectations subscales, 0.87 and in perceptions 0.77. A greater internal consistency was observed in the poll of expectations rather than in that of perceptions. Although low internal consistency was obtained in some dimensions, this does not affect the scale globally. The use of the instrument should be approached in a unidimensional way. Conclusion: The SERVQUAL scale presents an adequate psychometric performance and, therefore, is useful to assess the perceived quality of care in blood donors in the Colombian context, as long as it is approached in a unidimensional way.
