Anyone experienced with clinical trials?

I applied for a clinical trial for the Her2 Vaccine for women who have not had Herceptin. I found out my muga scan was 54 and I needed a score of 55 and my lymphocytes were 2.54 and I needed 3.0 or higher. I was not told to fast so I wonder if that affected my muga scan. Do lymphocyte counts vary or are they constant? I was extremely dejected...
