Sample Stability
- Hemolyzed or lipemic samples
- Improperly labeled or contaminated samples
- Samples not stored at recommended temperatures
- Insufficient sample volume
Understanding Your Results
Detected
CMV DNA is present, suggesting active CMV infection. Clinical correlation and further evaluation are recommended.
Not Detected
No CMV DNA detected, indicating no active infection at the time of testing. Repeat testing may be needed if symptoms persist.
Consult a doctor if you have symptoms of CMV infection, are immunocompromised, or if test results are positive for guidance on treatment and management.
Limitations
- ⚠Qualitative test does not quantify viral load
- ⚠False negatives possible in early infection or low viral levels
- ⚠False positives due to contamination or cross-reactivity
- ⚠Not suitable for monitoring treatment response quantitatively
Risks & Considerations
- ●Minor bruising or pain at the puncture site
- ●Rare risk of infection or fainting
- ●No significant risks associated with the test itself
Interfering Factors
- ●Contamination during sample collection or processing
- ●Improper sample storage or handling
- ●Presence of PCR inhibitors in the sample
- ●Recent antiviral therapy may affect detection

|---|---|---|---|---|
| Comparison | Cytomegalovirus (CMV) Qualitative PCR | Detects antibodies to CMV, indicating past or recent infection, but not active infection like PCR. | Measures viral load for monitoring treatment, whereas qualitative PCR only detects presence. | Traditional method slower and less sensitive than PCR; PCR is faster and more accurate. |
