Integrating Polymerase Chain Reaction/Electrospray Ionization Mass Spectrometry (PCR/ESI-MS), Iridica is capable of quickly identifying infection-causing pathogens directly from a patient’s sample, eliminating the need for culture.

Universite Libre de Bruxelles Intensive Care professor Dr Jean-Louis Vincent said: "Slower diagnostic methods, like cultures, have led to the overuse of broad-spectrum antibiotics and antimicrobials and an emergence of new resistant superbugs.

"By identifying pathogens faster with Iridica, a doctor can quickly prescribe the most effective therapy, potentially limiting the indiscriminate use of broad-spectrum antibiotics."

More than 1,000 infection-causing pathogens, such as bacteria, viruses or fungi, can be identified by the platform within six hours. Iridica demonstrated its ability to detect pathogens in Abbott’s RApid Diagnosis of Infections in the CriticAlly IlL (RADICAL) study.

The study also found that Abbott’s technology could help reduce health care costs by 30% as well as the hospital stay for people with serious infections by up to eight days.

Abbott Ibis Biosciences business R&D divisional vice-president Dr David J. Ecker said: "Currently, when a person enters a hospital with a suspected infection, it may take several days before the source can be accurately identified, which can delay appropriate treatment.

"Iridica can offer a better and faster way to detect and identify pathogens that cause serious infections and aid physicians in diagnosing and managing the critically ill."

The new platform offers five testing panels for pathogens that cause infections in the critically ill such as sepsis; other bacterial, fungal and viral infections; and ventilator-associated pneumonia.
