I just read a paper that says that it's very, very hard to tell the difference via DNA PCR testing when a bird has had the Rispens vaccine-- that the vaccinated virus looks like MDV-1.
Anyhow I am going to the vet with my possible Marek's rooster tomorrow and I can ask her to assist in a blood draw, if you find anything out before I go. He had the HVT vaccine only.
I'll forward you the info as soon as he answers me with the instructions. Good luck with your rooster tomorrow. Is he still the same? I keep hoping that it isn't Marek's.... I know it's possible that the vaccine might not work but I wanted to believe that it would. I can only imagine how you feel. I am going to be holding my breath when I put the remainder of my birds outside.
How does one check for elevated lymphocytes? Is it something that could be done at home with a scope, centifuge and misc lab equipment?

When I went in with Trousers, my roo that died last year, they did a visual count via microscope, and compared it to a normal "expected" count. His were three times as high as a normal count.
I am not sure what normal levels are, though. If you would like I can ask the process tomorrow, if I remember. I already have a list a mile long to ask about!!
Sounds like something I can learn... Don't have the lab set up yet, so don't worry about asking, I'll figure it out later.
