Overview

Severe pneumonia—including community-acquired (CAP), hospital-acquired (HAP), and ventilator-associated pneumonia (VAP)—remains a leading cause of morbidity and mortality.

Why this matters:

  • Rapid and accurate pathogen identification:
    • Supports antimicrobial stewardship
    • Improves patient outcomes
    • Aids infection control
    • Helps tailor antibiotic therapy

About the Panel

The Biofire® FilmArray® Pneumonia Panel Plus is an FDA-cleared, CE-marked, multiplex nucleic acid amplification test for simultaneous detection of multiple pathogens and resistance markers.

Sample types:

  • Sputum-like specimens: Sputum and tracheal aspirates
  • Bronchoalveolar lavage (BAL)

Turnaround time:

  • ~1 hour from sample loading

Specimen mnemonic:

  • PNEUMOPCR

Laboratory TAT:

  • 6 hours from receipt

    • Sensitivity: 96.3%
    • Specificity: 97.2%
  • Bronchoalveolar lavage specimens:
    • Sensitivity: 96.2%
    • Specificity: 98.3%

Semi-quantification bins for bacteria:
10⁴, 10⁵, 10⁶, and ≥10⁷ copies/mL

Important Notes & Considerations

  • Interpret results carefully, especially in patients with:
    • Prior hospital admissions
    • Recent or ongoing antibiotic use
    • Colonisation rather than active infection
  • The panel detects DNA/RNA, not viability—positive results may reflect non-viable organisms.
  • Only the resistance genes listed are detected.
    • Culture remains essential for full susceptibility testing.
  • Pathogens NOT detected by this panel (consider additional testing for):
    • Mycobacterial species
    • Cytomegalovirus (CMV)
    • Pneumocystis jirovecii
    • Aspergillus species
    • Stenotrophomonas maltophilia
    • Burkholderia cepacia complex
    • Less common Enterobacterales linked to HAP/VAP
  • Semi-quantitative data may overestimate pathogen load and may not match culture results.

🔍 Discuss complex or multi-pathogen results with your microbiologist.
