Understanding Your Results
Positive
Suggestive of recent or acute CMV infection. Correlate with clinical findings and consider additional tests.
Negative
No detectable CMV IgM antibodies. Does not rule out past infection.
Equivocal
Results are inconclusive. Retesting in 2-4 weeks is recommended.
If you have symptoms of CMV or are at high risk (e.g., immunocompromised, pregnant, transplant recipient), consult your healthcare provider for testing and advice.
Limitations
- ⚠A positive CMV IgM test does not necessarily confirm an active infection, as IgM antibodies can persist for months after an acute infection.
- ⚠Additional tests (e.g., CMV PCR) may be needed to confirm active infection.
- ⚠False positives or negatives can occur due to cross-reactivity or timing of sample collection.
Risks & Considerations
- ●Slight pain or bruising at the puncture site.
- ●Rarely, infection or hematoma.
Interfering Factors
- ●Cross-reactivity with other herpesviruses
- ●Timing of sample collection relative to infection onset
- ●Immunocompromised status may affect antibody response
