    Urinalysis is the second most common laboratory test, and its proper performance during the process, especially in the evaluation of urinary sediment, is essential. The goal of our study was to determine the influence of the time and angle of inclination of the centrifuge tube during the decantation process on the leukocyte count in urinary sediment. A descriptive, cross-sectional, prospective experimental study was conducted, collecting 100 urine samples from patients at a private clinic in northern Lima. All samples met the inclusion criteria and quality control standards, and the leukocyte counts were evaluated according to the Clinical Laboratory Standards Institute (CLSI) GP16-A3 protocol. From the total samples, 89% were women. The frequency of cases with or without variation in the leukocyte count, at decantation angles of 135º and 180º and times of 2 and 1 seconds, showed that 12% and 23% had the same count (p=0.040). A significant influence of the time and angle of inclination of the centrifuge tube during decantation on the leukocyte count in the urinary sediment was determined.
