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 HIV, HCV, HBV, HAV, parvovirus B19 and West Nile virus.

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.

A modular design that allows expansion with ready to use reagents, integrated back-up capabilities, and built-in contamination control to meet increased testing demands.
