26083 Epstein-Barr Virus DNA Detection & Quantification, Plasma (EBVQU)

Epstein-Barr Virus DNA Detection & Quantification, Plasma (EBVQU)
Test Code: EBVQUSO
Synonyms/Keywords
EBV, Infectious Mononucleosis, Viral Load, Post Transplant Lymphoproliferative Disorder (PTLD)
Useful For

Diagnosis of posttransplant lymphoproliferative disorders (PTLD), especially in EBV-seronegative organ transplant recipients receiving antilymphocyte globulin for induction immunosuppression and OKT-3 treatment for early organ rejection.

Monitoring progression of EBV-associated PTLD in organ transplant recipients.

Interference

Nonsymptomatic EBV viremia or viral shedding may occur occasionally in healthy individuals. Therefore, this test should be used only for patients with a clinical history and symptoms consistent with EBV infection, and must be interpreted in the context of patient's clinical history, signs and symptoms. This test should not be used to screen asymptomatic patients.

Only plasma specimens are acceptable for testing with this assay, and lipemic plasma specimens may result in reduced assay sensitivity or assay failure.

Test Information

Serial determination of plasma specimens from organ transplant recipients may be necessary to monitor increasing (risk of development of posttransplant lymphoproliferative disorders: PTLD) or decreasing (treatment efficacy) levels of Epstein-Barr virus (EBV) DNA.

Due to potential differences in assay performance, serial monitoring of a patient's EBV viral load should be performed using the same exact assay.
