@MrsPramm - I think most qualified cytologists are involved in research as well as helping to identify samples. And it's not like all the samples they'd be identifying would be the same cell type.
I think it would be a fairly satisfying job, actually, although I'd be worried about the responsibility. I know that they probably have to ID different cancer cells and so forth for patients and sometimes they get it wrong (because they are only human).
I'd hate to have that on my conscious, especially if it's a false negative. I've heard of people who got a false negative and ended up dying because they didn't get the treatment in time.
