Automation of the gold standard¹

The cobas® u 701 microscopy analyzer automates manual microscopy, the gold standard1 in urine sediment analysis. The analyzer standardizes and automates all manual steps, removes operator intervention, and increases efficiency.2

Benefits at a glance

The automation provided by the cobas u 701 microscopy analyzer minimizes operator intervention and improves turn around time (TAT) for sediment analysis. It standardizes all steps of the process, leading to repeatable and reliable results.

The cobas® u 701 microscopy analyzer uses a digital microscope to take high-power field (HPF) images that are known from manual microscopy. The system automatically analyzes the particles of these images with a neural network-based algorithm. The operator can simply validate the results and perform advanced result evaluation directly on the user interface of the analyzer.

The cobas u 701 microscopy analyzer uses a database with reference images to evaluate the 11 individual sediment particle types in the digital image. A multicenter evaluation proved the accuracy and reliability of the system performance.3
