- Improper labeling
- Sample leaked or broken
- Sample not in viral transport medium
Understanding Your Results
Detected
Positive for Influenza B RNA. Active infection likely. Clinical correlation and treatment as per physician.
Not Detected
Negative for Influenza B RNA. No evidence of infection. However, false negatives possible; clinical correlation advised.
Consult a doctor if you have flu-like symptoms, especially if you are in a high-risk group, or if symptoms worsen or persist beyond a week.
Limitations
- ⚠Qualitative test does not quantify viral load
- ⚠False negatives possible if sample collected too early or late in infection
- ⚠May not detect other respiratory viruses
- ⚠Results should be correlated clinically
Risks & Considerations
- ●Minimal risk of discomfort during swab collection
- ●Rarely, minor bleeding from nasal swab
- ●No serious complications
Interfering Factors
- ●Improper sample collection (insufficient epithelial cells)
- ●Sample stored incorrectly (delayed processing, wrong temperature)
- ●Recent antiviral therapy may reduce viral load
- ●Contamination during collection or processing
