Abstract
<p>In April 2020, our hospital introduced AUTION EYE AI-4510 (AI-4510), a urine sediment analyzer using image analysis method by ARKRAY company, with the aim of improving operational efficiency. In AI-4510, components that could not be determined as various cell components are quantified and classified as unclassified. We examined the relationship between this unclassified measured value (unclassified value) and the ratio of other cellular components. Measured 5,616 requested urine sediment samples with AI-4510 and microscopy. Based on the unclassified value of AI-4510, group A: 0.0–9.9 cells/μL (1,676 cases), group B: 10.0–19.9 cells/μL (1,294 cases), group C: 20.0–49.9 cells/μL (1,308 cases), Group D: Classified into 4 groups of 50.0 cells/μL or more (1,338 cases), and compared the concordance rates of both measurement methods for 5 components (red blood cells, white blood cells, squamous epithelial cells, hyaline casts, and bacteria) using a multiple comparison test. As a result of calculating the concordance rate with the microscopic method for various sediment components by unclassified value, it became clear that the lower the unclassified value in the above five items, the higher the concordance rate between AI-4510 and the microscopic method. Therefore, AI-4510 can be used to determine the necessity of microscopic examination, which is generally performed by cross-checking qualitative results and mechanical methods, using unclassified values as an index.</p>
