Laboratory test results demonstrated unremarkable hematologic, metabolic, hepatic, thyroid, autoimmune, and inflammatory profiles. Infectious disease screening and toxicology results were negative, with the exception of serologic evidence of a primary EBV infection, indicated by positive VCA IgM and IgG with negative EBNA-1 IgG. This evidence concerns the gene CD40LG and Epstein-Barr virus infection.
