    Urine analysis is the first and most important laboratory test in evaluating a patient with suspected kidney disease, providing valuable data. Examination of urinary sediment is especially useful for diagnosing urinary tract infections, particularly when detecting asymptomatic bacteriuria, and can also be done using the Neubauer chamber for leukocyte counts. Objective: To determine the relationship between leukocyte counts obtained by the sedimentation method and the Neubauer chamber method in urine samples collected at the Instituto Materno Perinatal (INMP) Clinical Laboratory in Lima in 2017. Materials and Methods: A selection of 68 urine samples from pregnant women was made. This is a quantitative, correlational, and prospective study, using the Pearson correlation test to analyze the relationship between leukocyte counts from sediment and the Neubauer chamber method. Results: A correlation value of 0.730 was found between the sedimentation method and the Neubauer chamber method. The Neubauer chamber achieved 100% sensitivity, 32.6% specificity, 46.3% positive predictive value, 100% negative predictive value, and 57% diagnostic certainty, with positive and negative likelihood ratios of 1.48 and 0, respectively. Conclusion: A good correlation was found between the sedimentation method and the Neubauer chamber method for identifying leukocytes, demonstrating that despite a good correlation, the Neubauer chamber does not apply as a diagnostic test.
