Abstract

Performance Evaluation of KU-F40 Automatic Feces Analyzer by Hongbo Zhang, Hui Zhang, Ming Huang, Chi Zhang, Yang Fei, Guo Li

Background: The performance of a new inspection system should be verified before it is used. The aim of this study was to analyze the performance of the KU-F40 automatic feces analyzer, which can serve clinic better.
Methods: A total of 1,822 fecal samples were collected at our hospital in September 2022 and tested by manual method and KU-F40 automatic feces analyzer. With manual microscopy as the gold standard, the clinical application value of KU-F40 was evaluated by sensitivity, specificity, coincidence rate, etc.
Results: For the KU-F40 automatic feces analyzer, the sensitivity of red blood cells (RBC), white blood cells (WBC), fungi, and occult blood (OB) was 95.08%, 92.68%, 89.47%, and 98.72%, respectively. The specificity was 99.38%, 99.83%, 99.94%, and 99.04%, respectively. The coincidence rates were 99.23%, 99.51%, 99.84%, and 98.96%, respectively. The Kappa values were 0.8883, 0.9415, 0.9181, and 0.9729, respectively. The p-values were 0.0574, 0.5078, 1.0000, and 0.1671, respectively.
Conclusions: KU-F40 automatic feces analyzer results are reliable, can effectively improve the efficiency of testing, reduce the risk of biosafety, which is accordance with the current clinical need. At the same time, continuous improvement should be made to better serve the clinic.
