cobas s 201 system

The first multi-dye NAT screening system

cobas s 201 system
Safe blood transfusions start with reliable screening

Blood donation management requires very careful planning and forecasting to predict demand. Since laboratories face constant pressure to be more efficient, there is a pressing need for flexible, scalable donor screening solutions.


Protect patients from infectious diseases with modular NAT screening

The cobas s 201 system is a complete nucleic acid testing (NAT) solution that supports the central needs of blood screening laboratories with assays covering West Nile Virus, HIV, HCV, HBV, HAV, and parvovirus B19.


Combining real-time PCR technology and modular automation, the cobas s 201 system minimizes hands-on time across the entire testing process, while multi-dye technology makes confirmatory testing obsolete.


Meet demand as it grows with a scalable modular design, ready-to-use reagents, integrated back-up capabilities, and built-in contamination control.

High scalability and impressive flexibility

  • Streamlines lab workflow
  • Real-time PCR allows amplification and detection of RNA and DNA within hours
  • Supports simultaneous multiple assay processing
  • Accommodates integrated backup to maximise lab productivity
  • Flexible, mix-and-match scalability helps NAT labs work more efficiently

Powerful pooling and data management (PDM) software

  • Provides built-in redundancy, full system audit and data security
  • Supports various pool sizes
  • Supports simultaneous pool creation to handle multiple assays
  • Provides multiple search and reporting options

Easy sample preparation, large load capacity

  • Automates every step of the RT-PCR-based blood screening process
  • Includes automated pooling using the Hamilton MICROLAB® STAR IVD Pipettor

Result integrity for all donor screening assays

  • Closed-tube format requires no user interaction after sample loading is completed
  • Reduces the risk of sample contamination
  • Software-guided workflow
  • Sample and reagent ID tracked throughout process
