Overview
The purpose of the RSV A, RSV B (RNA Detection) Qualitative Test is to confirm the presence of Respiratory Syncytial Virus in respiratory samples. It helps in diagnosing RSV infection, especially in high-risk populations such as infants, premature babies, and immunocompromised individuals. The test also distinguishes between RSV A and RSV B subtypes, which may have epidemiological and clinical significance. Early diagnosis allows for timely supportive care, antiviral therapy (if indicated), and implementation of infection control measures to prevent outbreaks in hospitals and communities.

- Insufficient sample volume
- Sample not in viral transport medium
- Sample leaked or contaminated
- Sample stored at room temperature for >24 hours
Understanding Your Results
Positive for RSV A
RSV A RNA detected. Indicates active RSV A infection. Clinical correlation advised.
Positive for RSV B
RSV B RNA detected. Indicates active RSV B infection. Clinical correlation advised.
Negative
RSV RNA not detected. Does not exclude infection if sample quality is suboptimal.
Consult a healthcare provider if you or your child experience symptoms such as persistent cough, wheezing, difficulty breathing, high fever, or bluish discoloration of lips/face. Early diagnosis and treatment are essential, especially for infants and high-risk individuals.
Limitations
- ⚠Qualitative test does not provide viral load quantification
- ⚠Negative result does not rule out RSV infection if sample quality is poor
- ⚠Results should be interpreted in conjunction with clinical findings
- ⚠May not detect other respiratory viruses
Risks & Considerations
- ●Minimal risk of bleeding or infection at collection site
- ●Slight discomfort during swab collection
- ●Rare risk of vasovagal response
Interfering Factors
- ●Improper sample collection or inadequate sample volume
- ●Delay in transport or storage at incorrect temperature
- ●Presence of inhibitors in the sample (e.g., blood, mucus)
- ●Contamination during collection or processing
