Clinical Indications

  • cobas® EBV is not intended for use as a screening test for the presence of EBV in blood or blood products or human cells, tissues, and cellular and tissue-based products (HCT/Ps).

  • Quantitation of EBV DNA may be affected by sample collection methods, patient factors (i.e., age, presence of symptoms), and/or stage of infection

  • cobas® EBV test results should be interpreted in the context of other clinical data and should not be the sole basis for treatment decisions.
