Homologación de resultados del análisis microscópico manual y automatizado de orina: una revisión bibliográfica

Abstract

Introduction: Urinalysis represents one of the most requested laboratory tests for the diagnosis and follow-up of urinary and renal system diseases. Although manual microscopy has been the traditional method, its process is characterized by being laborious and time-consuming. For this reason, automated systems have been introduced with the aim of improving the accuracy of the results. Objective: To establish the relevance of the homologation of manual and automated urine microscopic analysis results through a literature review. Methodology: This study is based on descriptive research of bibliographic documents with a retrospective analysis. For the collection of information, various databases such as PudMED, Scielo, Google Scholar, Scopus, Elsevier were consulted. During the bibliographic search, 25 articles related to the subject of the study were found, for which the PRISMA methodology was used. Results: by analyzing the different investigations, it was found that the automated analyzers showed an adequate concordance with manual microscopy for red blood cells, white blood cells and epithelial cells. However, in the case of bacteria and casts, a lower concordance was evidenced. Conclusion: Urine microscopic analysis is crucial in medical diagnosis. The transition from manual methods to automated equipment has improved the efficiency and accuracy of the results. The comparison between both methods is fundamental to ensure the reliability of the results, which contributes to provide safe and appropriate treatments for patients.
