Interpretation of the Viral Respiratory Panel Report

Doctors receive an easy to read “Detected” or “Not Detected” result for each pathogen.

2015 Nationally Notifiable Infectious Conditions ¹:

• Bordetella  pertussis
• Influenza-associated pediatric mortality
• Novel influenza A virus infections

Upper Respiratory Tract Infections (URTI)

Quick Facts

• Estimated economic impact of non- influenza related URTIs is $40 Billion annually in the US ²
• Adults average 2-5 upper respiratory tract infection each year while children average 7-10 upper respiratory tract infections a year.³

Overlapping Signs and Symptoms:

• Coughing
• Nasal Discharge
• Congestion
• Fever
• Wheezing
• Headache
• Myalgia

Comprehensive, Accurate, and Fast Results May…

• Improve patient management.⁴
• Prevent secondary spread of infection.⁵
• Prevent the use of unnecessary antibiotics.⁶
• Provide more timely and effective treatment.⁴
• Lead to shorter hospital stays.⁶

Sample Requirements:

Nasopharyngeal swabs (NPS) collected in viral transport media

• NPS specimens should be collected according to standard technique and immediately placed in viral transport media (VTM).⁷
• ~300µl of sample is required for testing.
• If storage is required, specimen in VTM can be held at room temperature (18- 30 °C) for up to 4 hours, at refrigerator temperature (2-8 °C for up to 3 days, or at freezer temperature (<-15 °C) for up to 30 days

Quick Facts

• Each year in the US, 2 million people acquire serious bacterial infections that are resistant to one or more prescribed antibiotics, and at least 23,000 people die as a direct result of these antibiotic- resistant ⁸
• An estimated 55% of antibiotic prescriptions for Acute Respiratory Tract infections are ⁹
• The misuse of antibiotics costs the US healthcare system over $20 billion each year.¹⁰

Implications of Antibiotic Resistance

• Increases mortality and morbidity from untreatable diseases
• Increases risk of global spread of pathogens
• Results in longer, more frequent hospital stays
• Limits drug options at a time when pharmaceutical companies are developing fewer new antimicrobials
• Increases cost of research for new drugs

The FilmArray brings infection control, antimicrobial stewardship, infectious disease clinicians and pharmacy together. We work as a unit, a team.”
