Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The real-time reporting of PCT results along with viral PCR data from the FilmArray® Respiratory Panel 2 plus in conjunction with an antimicrobial stewardship plan will aid in the proper withholding or withdrawing of antibiotics (ATB) when the collective data is indicative of a viral Lower Respiratory Tract Infection (LRTI).

The addition of the FilmArray® RP2plus diagnostic test indicating the presence of a viral infection in subjects presenting with respiratory symptoms could improve the confidence to care-providing physicians to withhold prescribing antibiotics.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In the emergency room a nasopharyngeal swab sample will be collected from subjects with a suspected LRTI for the FilmArray respiratory panel assay plus a blood sample for the PCT assay if the PCT measurement has not been already prescribed.

The FilmArray® Respiratory Panel 2 plus (RP2plus) is a multiplexed nucleic acid test intended for use with FilmArray® 2.0 or FilmArray® Torch systems for the simultaneous qualitative detection and identification of multiple respiratory viral and bacterial nucleic acids in nasopharyngeal swabs (NPS) obtained from individuals suspected of respiratory tract infections.

Both results will be reported in real-time to the treating physicians with the recommendation to withhold or withdraw antibiotics if:

1. PCT\<0.10 µg/L with either a positive (with a viral respiratory pathogen) or negative FilmArray assay or
2. PCT\<0.25 µg/L and FilmArray positive with a viral respiratory pathogen. For the control arm, patients will benefit from the usual care of patients with suspected LRTI at the discretion of the attending physician. Care may entail a CRP and/or a PCT measurement, but no nasopharyngeal swab sampling.
