Reference range
Reference ranges are laboratory-specific and not well-established; results should be interpreted in the context of the patient's clinical status, CMV serostatus, and immune competence. Generally, values are reported as absolute counts per microliter or as percentage of total CD8+ T cells.N/A
No special patient preparation required. Recent immunosuppressive therapy (corticosteroids, calcineurin inhibitors, biologics) may affect results and should be noted. Patients should be advised about the importance of recent clinical history including CMV status, transplant status, or HIV status.
