Focus on what matters

The cobas® b123 POC system is a fully automated system for testing of blood gases, electrolytes, metabolites, hematocrit, total hemoglobin and its derivatives, oxygen saturation, and neonatal bilirubin.1

With flexible configurations and a throughput of up to 30 samples per hour, the cobas b 123 POC system can easily be customized to the clinical needs of the intended care unit (ICU), emergency room (ER), neonatal intensive care unit (NICU), operation room (OR), dialysis units, or the laboratory.

The cobas b 123 POC system supports you in managing high demand with low personnel resources and making the right decisions with a fast and easy blood gas result.

  • A touch screen and integrated printer mean that the analyzer can fit into departments where space is limited
  • Broad parameter panel to meet various parameter combinations
  • Measure whole blood, dialysis solutions, and aqueous solutions—from full to micro sample volume with syringe or capillary—to fulfill the needs of critical patient care
Flexible line icon illustrating the increased flexibility with the cobas b 123 system.
  • Different instrument, sensor cartridge, and fluid pack configurations allow flexibility for different sample throughputs and parameter needs
  • AutoQC and oximeter modules are available as optional features
  • Transferable consumables between instruments reduce the waste of tests and offer flexibility in inventory management
  • Optional mobile cart enables easy movement to the point of need
Check mark icon illustrating the simplicity of the cobas b 123 system.
  • No preventative maintenance: No regular preventative maintenance from professional service is requested. All traditional routine maintenance parts are contained in the fluid pack, and the sensor cartridge is designed for minimal maintenance. The system is always ready for the next measurement.
  • Automated clot elimination:The system detects clots before they reach the sensor and diverts them to the waste container, reducing downtime and avoiding manual clot removal. No special syringes or consumables (e.g. clot catcher) with additional costs are needed.
  • Integrated consumables: Three consumables — sensor cartridge, fluid pack, and AutoQC — are combined to streamline operations. The sensor cartridge supports up to 10 parameters, while the fluid pack contains all five working solutions and two waste storages to minimize the frequency of consumable replacement.

  • Differentiate between acute and chronic patient conditions in complex environments such as the ER or ICU
  • Rapidly identify metabolic and respiratory acid-base disturbances without the need for a calculator

Arterial blood gas is the gold standard for acid-base and blood gas testing in critical care. However, arterial punctures are complex, painful for the patient, and come with a risk of side effects such as hematoma and infections.

Roche v-TAC software calculates arterial blood gas values from venous peripheral blood gas measurement results obtained in a blood gas analyzer (such as cobas® b 123 and cobas®b 221), combined with arterial oxygen saturation (SpO2) measured by a pulse oximeter.

Roche v-TAC may contribute to clinical, workflow, and patient benefits.

  • Improve patient experience by offering an alternative to the painful arterial punctures
  • Optimize the blood gas testing workflow
