. . . now at physicians' fingertips

Roche has pioneered the advancement of polymerase chain reaction (PCR) analysis, now recognized as a gold standard in laboratory diagnostics.

• Proprietary, Nobel Prize-winning technology
• Identifies infectious diseases by replicating DNA or RNA extracted from patient samples
• High sensitivity and specificity across assays reduces the risk of false negatives and false positives

Recognized as one of the most important scientific advances of the 20th century¹, polymerase chain reaction (PCR) is a quick, easy way to create unlimited copies of DNA or RNA from just one original strand.

In large molecular laboratories, PCR analysis can be performed on many samples simultaneously—a multi-step process requiring a skilled technician.

The cobas Liat System fully automates these steps for the rapid analysis of a single sample, making it ideal for time-sensitive in-office diagnoses.

No operator intervention or interpretation required.

• Each cobas Liat assay tube contains a set of chemical reagents used in the detection of DNA or RNA sequences unique to a particular infectious disease
• Inside the cobas Liat Analyzer, pressure and heat are precisely applied to the tube segments, mixing the sample and reagents in a prescribed sequence
• DNA or RNA from within the sample is amplified and analyzed to detect and identify disease
• An accurate positive or negative result is generated in 20 minutes or less
