I had an EBV blood test done to diagnose chronic fatigue syndrome, it can back positive at >8.0. Does that mean I am contagious? Really worried

No. What you talking about probably igg level , this stay positive after infection. You may have past infection . You should see infectious disease physician. May need ebv pcr .
Not necessarily. I need more information; there are 4 different types of antibodies to ebv. Most indicate past rather than current infection. You are only contagious if the antivca igm antibodies are positive. Ebv infection causes acute mono & the virus remains in our bodies for years but ebv is generally not the cause of chronic fatigue syndrome & ebv tests don't diagnose it.
