ebv levels
My levels are as follows:
igm ab < or = 0.90
igg ab 2.51
ebna ab igg 3.99
what does this all mean? I have just been tested for ebv for the first time and I don't know if this means I am acitve with the virus?

IgM to the viral capsid antibody appears early-on with an infection, disappearing after 4 - 6 weeks. Your IgM level does not seem significant enough to indicate the early stages of an EBV infection, though I'd have to see what the range was for that test result in order to really say for certain.
The IgG to the viral capsid antigen typically appears in the acute phase of an EBV illness, peaking at 2 - 4 weeks after onset, but then declining a little and remaining with you for the rest of your life. Thus, your "igg ab 2.51" value, which I'm assuming means IgG to the VCA (viral capsid antigen) could indicate past infection. If this is IgG to the early antigen, however, this typically occurs in the acute phase of the illness and falls to undetectable levels within 3 - 6 months. Detection of antigen to the early antibody usually means a current EBV infection for most people, but up to 20% of healthy people have this antibody crop up in their bloodwork for years.
The antibody to the EBV Nuclear Antigen (EBNA) appears 2 - 4 months after you're first infected with EBV, and then also persists for the rest of your life--this value will not differentiate between a past or current infection.
In short, based upon your lab values (if I've interpreted them correctly), it's not possible to tell whether or not you have an active EBV infection, but my best guess would be that you don't. The only thing that could change this is the IgG AB value--if this means the antibody to the "early antigen", rather than the "viral capsid antigen". If it's the antibody to the early antigen, you may have an active infection; if it's the antibody to the viral capsid antigen, you likely do not have an active infection.
Hope this helps! I know it can be confusing...
