Understanding Your Results
Detected
Active BK or JC virus infection is present. Clinical correlation is needed for diagnosis and treatment planning.
Not Detected
No active BK or JC virus infection detected. If symptoms persist, further testing or clinical evaluation may be required.
Consult an infectious disease specialist or your healthcare provider if you have symptoms of viral infection, a weakened immune system, or if test results are positive for timely management and treatment.
Limitations
- ⚠Qualitative test only; does not measure viral load or quantify infection
- ⚠May not detect very low levels of virus or latent infections
- ⚠Cross-reactivity with other polyomaviruses is possible but rare
- ⚠Results should be correlated with clinical symptoms and other tests
Risks & Considerations
- ●Minimal risk from blood draw, such as bruising or soreness at the puncture site
- ●Very low risk of infection from needle insertion
- ●No significant risks associated with urine sample collection
Interfering Factors
- ●Presence of PCR inhibitors in the sample (e.g., hemoglobin, urea)
- ●Contamination during sample collection or processing
- ●Improper sample storage or transport
- ●Recent antiviral therapy may affect detection
