Urinary Tract Infection Research Result

  • Yonsei University's Department of Laboratory Medicine has conducted clinical research and published a paper (ASM Journal)

  • The medical device equipment inspection for GMP certification and KFDA approval has been completed by KTL


  • Project Details:

  • Performance parpameters for the prediction of positive urine culture in two subsets(overall and trained-species set) according to the tow cutoff values for positive urine culture

    (June 1, 2019 - December 31, 2020, Ministry of Trade, Industry and Energy > Korea Institute for the Advancement of Technology)

  • 2022' Conference Presentation on Researcher Clinical Results for UTI Analysis Equipment (Bacometer)

  • The study analyzed the same urine samples from a total of 263 patients using both the traditional culture method and the Bacometer.

  • When the infection threshold was set at 5,000 cfu/ml, the Bacometer demonstrated a sensitivity of 100% and a specificity of 98.3%, outperforming FDA-approved products. Additionally, the Bacometer reduced the testing time to 30 minutes, a significant improvement compared to the 24 hours required by traditional culture methods.
