Bloods just came back EBV Positive

My numer is 8.0 - seems mighty high to me considering positive = >1.0 and negative = <0.9.  My doctor said it could be an 'old infection' and didn't seem to think it's very important.  I believe I've had it for a very long time as I was exposed to it from 1979 - 1982 by a boyfriend who I didn't know had it until he left town and his cousin told me that he did.  I've been suffering with autoimmune symtpoms for which I've been getting assorted tests.  I'm really sick and have been for many, many years with no positive dx.  Can anyone who has it tell me what they suggest I do next?  I do have an appt with a rheumitologist on 3/25, and I guess my pcp thinks I should get help from that doctor.  That's a few weeks away and I'd love to learn more about this illnes in the meantime.  Thanks so much!
