@chickie001 Thanks for posting the reference ranges. It looks like they are all elevated so likely an active infection with EBV. The IgM antibodies are positive when there is an active infection but not always. IgG will usually remain elevated for life even in healthy individuals. I'm glad your doctor actually recognized that the EBV is active. Mine told me to exercise despite having extremely elevated titers across the board and debilitating symptoms. She's no longer my doctor, of course! Again, http://www.ebvhelp.com is a good resource, along with http://www.rawlsmd.com. Listen to your body. THIS IS NOT AN ILLNESS THAT IMPROVES BY PUSHING YOURSELF! I've learned that the hard way. ....God bless
