Well seeing how some people have confessed to embarrassing mistakes on their part, I will confess mine. In my defense, I was not even an MT student yet, but I had started to work in the Micro lab doing receiving samples and doing simple setups. I started working there over the summer before the MT course began so I was very very fresh.... A doctor and her resident walk in and hand me a sample and say: I'd like EB testing done on this please" And I look at her and say: Ebola virus? No she says, Epstein Barr Virus... how stupid did I feel?!
