- Leaking or damaged containers
- Samples without viral transport medium
- Delayed transport beyond stability period
Understanding Your Results
Detected
RSV B RNA is present, indicating an active RSV B infection. Consult a healthcare provider for appropriate management.
Not Detected
RSV B RNA is not detected. If symptoms persist, consider retesting or alternative diagnoses.
If the test result is positive, consult a doctor immediately for treatment options. If negative but symptoms worsen or persist, seek medical advice for further evaluation.
Limitations
- ⚠May not detect all RSV B strains due to genetic variations
- ⚠False negatives possible if viral load is very low
- ⚠Does not quantify viral load; only qualitative detection
- ⚠Cannot distinguish between active infection and residual RNA
Risks & Considerations
- ●Minor discomfort during swab collection
- ●Rare risk of nosebleed or gagging
- ●No significant risks associated with the test itself
Interfering Factors
- ●Improper sample collection or handling
- ●Contamination during transport
- ●Recent antiviral therapy may reduce viral load
- ●Sample degradation due to delayed processing
