Automated urine sediment analyzer DxU

for clinical diagnosticbenchtopwith barcode reader

Overview
The DxU Microscopy Series automates urine sample microscopy using Digital Flow Morphology with Auto-Particle Recognition (APR) software to capture, classify and store digital particle images, reducing manual review and improving laboratory throughput.

Key features

• Automated urine microscopy (standalone module or integrated with DxU 810c Iris to form the DxU Iris Workcell automated urinalysis system)
• Digital Flow Morphology measurement with APR software for image capture and classification
• Edit-Free Auto-Release to auto-verify true positive and true negative results for walkaway operation
• iWARE integrated urinalysis software for onboard validation and result verification
• iQclear cleaning aspiration module to optimize rinse routine and probe cleaning
• Reduces manual microscopic review rates to <3% when configured as DxU Iris Workcell

Models / Variants

• DxU 850m Iris — throughput: 101 samples per hour
• DxU 840m Iris — throughput: 70 samples per hour
• Accessories and installation kits (various load/unload and install SKUs referenced on the product page)

Particle classification (primary categories and additional subclassifications)

• Primary categories: RBC, WBC, WBC clumps, squamous epithelial cells, non-squamous epithelial cells, hyaline casts, unclassified casts, crystals, bacteria, yeast, sperm, mucus
• Additional subclassifications include:
  • Unclassified casts: granular, cellular, waxy, broad, RBC, WBC, epithelial cell, fatty casts
  • Crystals: calcium phosphate, uric acid, calcium carbonate, leucine, cystine, tyrosine, amorphous calcium oxalate, triple phosphate
  • Non-squamous epithelial: renal epithelial, transitional epithelial
  • Yeast: budding yeast, yeast with pseudohyphae
  • Other: RBC clumps, fat, oval fat bodies, Trichomonas, dysmorphic RBCs

Measurement technology & workflow impact
Digital Flow Morphology combined with APR captures and evaluates image features (size, shape, contrast, texture) to classify particles into primary categories with operator options for subclassification. The approach leverages image review to substantially reduce manual microscopy and total sample processing time compared with manual methods.
