Okay so I always feel ill all the time and keep thinking that there is something wrong with me, my mum just says that I'm a hypochondriac and I think I agree with her :P But I'd rather be on the safe side just in case.
Anyway my question.. I want to be checked for alot of things with a blood test but I don't know what I want to be checked for. Can I ask for a blood test from the doctor and get them to check for anything or do I have to know what I want to be checked for?
