Test Parameters & Specifications
Sample Stability
- Insufficient sample volume
- Improperly labeled or hemolyzed samples
- Samples collected in incorrect tubes
- Delayed shipment beyond stability period
Understanding Your Results
Not detected (Negative)
No CMV DNA found; suggests no active infection or viral load below detection limit.
Low viral load (e.g., <1000 copies/mL)
Mild infection; may require monitoring or treatment based on clinical context.
High viral load (e.g., >10,000 copies/mL)
Severe active infection; high risk of complications; immediate medical intervention recommended.
If you experience symptoms like persistent fever, fatigue, or swollen glands, or if you are immunocompromised with a positive test result, consult an infectious disease specialist promptly for appropriate management.
Limitations
- ⚠Cannot distinguish between active and latent infection
- ⚠Sensitivity may vary with viral load levels
- ⚠Not suitable for detecting past infections; antibody tests are needed
- ⚠False negatives possible in early infection stages
Risks & Considerations
- ●Minor bruising or pain at the puncture site
- ●Rare risk of infection or dizziness
- ●No significant long-term risks
Interfering Factors
- ●Hemolyzed or lipemic samples may affect accuracy
- ●Improper sample storage or handling
- ●Recent antiviral therapy may suppress viral load
- ●Contamination during collection
