5 Reasons Labs Choose the Roche Cobas U601 for Automated Urine Strip Analysis
Urine strip testing looks simple, but at volume it is one of the most labor-intensive and variable workflows in the lab. Dipping strips, timing incubation, and reading color changes by eye ties up technologists and introduces operator-to-operator differences in every read.
The Roche Cobas U601 automates the entire strip workflow. Roche describes it as a fully automated urinalysis system, and it handles strip dispensing, incubation, and reading without a technologist at the bench.
Here are 5 reasons labs choose the Roche Cobas U601 for automated urine strip analysis.
1. Fully Automated Strip Handling
The U601 uses a cassette (the cobas u pack) that holds 400 test strips, and the analyzer dispenses a single strip for each sample. Combined with automated sample handling, that removes the manual dipping and timing steps that slow down a busy urinalysis bench.
2. Camera-Based Strip Reading
Instead of relying on a technologist's eye, the U601 uses reflectance technology and takes high-resolution images of the strip pads through a camera chip built into the photometer. The system evaluates those images itself, so strip reading no longer depends on who is working the bench that shift.
3. Up to 240 Samples per Hour in a Benchtop Footprint
The U601 processes up to 240 samples per hour with a 15-second sample cycle time, in a benchtop unit measuring about 69 cm wide by 53 cm deep. That is substantial capacity for a lab handling hundreds of urine samples a day without giving up a large amount of bench space.
4. A Full Chemical Profile
The analyzer reports pH, leukocytes, nitrite, protein, glucose, ketones, urobilinogen, bilirubin, and erythrocytes, along with specific gravity, color, and clarity. Diamond's refurbished U601 lists 12 tested parameters and stores 10,000 patient results and 300 QC records onboard.
5. A Path to Automated Sediment Analysis
Roche designed the U601 to pair with the Cobas U701 microscopy analyzer. The two can be upgraded on-site to form the cobas 6500 urine analyzer series, a single platform with automated sample transportation of up to 116 samples per hour. Labs that start with strip testing can add automated sediment analysis later, and our look at how the U701 automates urine sediment analysis covers that side in detail. For smaller labs with workloads of roughly 30 to 100 samples a day, the semi-automated Cobas U411 may be a better fit.
