Test before you treat

Take charge of antibiotic prescribing
with the cobas® Liat® System

Antibiotics have transformed the practice of medicine, making once lethal infections readily treatable. However, the overuse or misuse of antibiotics has led to the rise of bacterial superbugs, which can be resistant to some forms of treatment. For antibiotics to remain effective, their use must be optimised.

The cobas® Liat® System brings laboratory-quality PCR technology right to the point of care, providing fast and accurate results you can trust across a growing number of respiratory infections.

Learn why testing matters

Diagnose confidently with the
cobas® Liat® System

Most upper respiratory tract infections are caused by viruses, where antibiotics have no beneficial effect. Studies from general practice have demonstrated high rates of unnecessary antibiotic prescribing for patients with these types of infections.1

Together with assessment of signs and symptoms, testing before treatment is an important step in determining the appropriate course of action. While most testing options offer a tradeoff between speed and accuracy, the cobas® Liat® System brings timely and reliable testing where it's needed most: the point of care.

Antibiotics used in medicine are largely prescribed
by general practitioners.

Primary care accounts for 80–90% of all antibiotic prescriptions in Europe, and most are prescribed for respiratory tract infections.2

However, sometimes they are prescribed for conditions
antibiotics cannot treat.

Of adults seeking treatment for respiratory infections in the US, a study found more than two thirds of antibiotics were most likely prescribed inappropriately.3

Antibiotic treatment is most effective when it's optimised.

cobas Liat system antibiotic rapid test

A study reports a 45% reduction in antibiotic prescribing in adults using rapid tests rather than signs and symptoms checks.4

Advanced diagnostics can help practitioners make informed
treatment decisions.

Increase diagnostic confidence with the cobas® Liat® System. Avoid the need to question a result, wait for answers, or rely solely on empiric treatment.

Small, swift, simple, and secure

There is a need for quick, well-informed treatment decisions at the point of care. On-site rapid antigen tests may be fast, but also have a lower rate of accuracy and require confirmation of negative results. Lab cultures are highly accurate, but have a long turnaround time—from 4 hours to 5 days.

The cobas® Liat® System offers a unique combination of speed, sensitivity and specificity. With a growing number of assays featuring turnaround times of 20 minutes* or less, this compact molecular solution supports effective clinical management.
