cobas u 701 microscopy analyzer

Automation of the gold standard1

cobas u 701 microscopy analyzer
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

 

Full automation and standardization of microscopy

 

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 which leads to repeatable and reliable results.

 

Providing digital images

 

The 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 an neural network based algorithm. The operator can simply validate the results and perform advanced result evaluation directly on the user interface of the analyzer.

 

Reliable counting performance

 

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