Verification of UriSed 3 PRO automated urine microscope in regional laboratory environment

Ten UriSed 3 PRO automated microscopes (77 Elektronika, Hungary) were verified for nine HUSLAB laboratories with 160 000 annual urine samples. Particle counting of the primary instrument was against reference visual microscopy 463 specimens, and culture on chromogenic agar plates parallel 396 specimens. Nine secondary instruments compared pairwise instrument. Relative imprecisions to Poisson distribution, R(CV), estimated be 1.0 white blood cell (WBC) 1.5 red (RBC) counts, respectively. Spearman’s correlations rS = 0.94 WBC, 0.87 RBC, 0.82 squamous epithelial (SEC) counts. Agreement (Cohen’s weighted kappa) 0.89 0.88 SEC, 0.59 combined casts, 0.49 non-squamous cells (NEC). Bacteria detected a sensitivity 90% specificity 39 at 107 CFB/L (104 CFU/mL). Created flagging limits allowed reporting 70–75% patient results. adopted into routine use after acceptance verification.
