A historic innovation
Since 1983, Roche has pioneered the advancement of PCR analysis, which is recognized as a gold standard in laboratory diagnostics. The cobas® Liat® PCR System replicates extracted DNA or RNA from patient samples to accurately identify infectious diseases. Using Roche PCR technology, laboratory-quality sensitivity and specificity are achieved across assays, significantly reducing the risk of false negative and false positive results.1

Quality without compromise
Patients deserve the best care possible—that means reliable results in a reasonably short amount of time. Current diagnostic options offer a trade-off between speed or accuracy, and since many diseases present similar symptoms at early stages, the need for a reliably accurate point-of-care testing solution is high.
