Objectives:
Urinalysis is a first-line test for screening for urinary tract infection. Several devices performing strip and sediment analysis have been introduced. The aim of this study was to compare the performance of Labsan Tricell-1000 and Dirui FUS-2000 automated urine analyzers with manual microscopy.
Methods:
463 urine samples were analyzed. Digital image processing and particle recognition automatically display the cells in a flowing sheath fluid mixed monolayer urine sample, take the pictures of particles via digital camera, analyse these pics with a particle recognition software, transfer images of the formed elements to the screen and allow well-trained personnel to select, reclassify or remove them. Manual microscopy was used for comparison.
Results:
Agreement between Tricell-100 and manual microscopy was very good for RBC (ϰ = 0.80), and WBC (ϰ = 0.83); good for CaOx (ϰ = 0.69), SEC (ϰ = 0.80), YLC (ϰ = 0.72), HC (0.69) and LC (ϰ = 0.64); moderate for BAC (ϰ = 0.51), APC (ϰ = 0.43) and MT (ϰ = 0.55); fair for GC (ϰ = 0.39) and RTEC (ϰ = 0.32).
Conclusions:
Labsan Trion TriCell-1000 demonstrated satisfactory performance and can be used in routine urinalysis. In the case of low counts of RBC, presence of yeast, crystal, casts or cell clumping in urine sediment, characterization of urine particles should be performed by manual microscopy.
