Understanding Your Results

Results indicate the presence or absence of CMV IgG antibodies. A positive result suggests past infection, while a negative result indicates no detectable exposure. Interpretation should consider clinical context and patient history.
📊

Positive (IgG detected)

Indicates past or current CMV infection. Immune status is established. Monitor for symptoms in immunocompromised patients.

📊

Negative (IgG not detected)

No evidence of past CMV infection. Susceptible to primary infection. Consider repeat testing if symptoms persist.

⚠️ When to Consult a Doctor:

If you experience persistent symptoms like fever, fatigue, or swollen glands, or if you are immunocompromised and receive a positive result, consult a healthcare provider for further evaluation and management.

Limitations

  • ⚠Results may be negative in early infection before antibody production
  • ⚠False positives can occur due to assay limitations

Risks & Considerations

  • ●Minor pain or bruising at the blood draw site
  • ●Rare risk of infection or dizziness

Interfering Factors

  • ●Hemolyzed or lipemic samples may affect accuracy
