Background: The urine sample, for some laboratory tests, is collected by the patient himself and it is the responsibility of the laboratory staff to guarantee the quality of the pre-analytical process that ensures its usefulness for the diagnosis and monitoring of multiple diseases. Objective: To evaluate the pre-analytical phase in the 24-hour urine collection in the central laboratory of a hospital in Lima. Material and methods: Descriptive and cross-sectional study that included patients who attended the Cayetano Heredia Hospital. With the support of the participants, a data collection form was filled out based on the identification of critical points in the 24-hour urine collection of Ruiz et al, and on the standardized guide GP16-A3 and GP16A2 of the CLSI. An Excel sheet was used to carry out the frequency analysis and the bar graphs. Result: 394 24-hour urine samples were obtained, 17 (4.3%) were rejected by the laboratory for the main reason of inadequate sample collection (94.1%). The most frequent pre-analytical error associated with health personnel was the lack of annotation of the age on the bottle (90.98%), while the most frequent error by the patient was the inadequate labeling of the start and end time of the collection (97.1 %). Conclusion: The standardization of rejection criteria is necessary, and the improvement in the orientation of patients for better adherence to the recommendations of laboratory personnel.
