Multiplex viral polymerase chain reaction testing using the FilmArray device compared with direct fluorescent...

Area of Science:

• Molecular diagnostics
• Clinical microbiology
• Laboratory automation

Background:

• Advancements in instrument design have automated complex molecular assays.
• The FilmArray Respiratory Panel (RP) is an automated nested polymerase chain reaction (PCR) assay for detecting multiple respiratory pathogens.

Purpose of the Study:

• To compare the workflow efficiency of the FilmArray RP assay with direct fluorescent antibody (DFA) staining.
• To evaluate the performance and ease of use of the FilmArray RP for respiratory pathogen detection.

Main Methods:

• Comparative workflow analysis between FilmArray RP and DFA staining.
• Quantification of total touches and hands-on time for each method.
• Assessment of the number of detectable respiratory organisms and required training.

Main Results:

• FilmArray RP required significantly fewer total touches (91) and less hands-on time (4 min 52 sec) compared to DFA staining (502 touches, 12 min 45 sec).
• FilmArray RP detected a broader range of targets (20 viruses and bacteria) versus DFA staining (7 viruses).
• FilmArray RP required less user training than DFA staining.

Conclusions:

• The FilmArray RP assay offers a highly efficient and user-friendly molecular diagnostic solution for respiratory pathogen detection.
• Its automation and ease of use make it suitable for continuous operation in clinical and point-of-care settings.
• FilmArray RP provides comprehensive pathogen identification with reduced laboratory workload.
