  • Liver biopsy in patients with CMV often demonstrates mononuclear cell infiltration of the portal areas but may also reveal granulomatous inflammation or microabscesses[Ten Napel 1984]
  • Qualitative diagnostic assays, such as the CMV immunoglobulin M (IgM) test, can be falsely positive
  • Therefore, quantitative diagnostic assays for CMV are essential for diagnosis, including molecular assays (PCR and other amplification assays) and antigen-detection (pp65 antigenemia) assays (Management Guidelines)[Razonable 2013]
