Sorry I'm just getting use to this site and how to reply! I am wanting to start off with easier ones and get more complicated. I'm trying to prepare for exams at a higher level which will include complicated case studies. I think both serological testing and clinical would be helpful? I am at Specialist level now but never worked in a reference lab and struggle with pan reactive panels and eluates/adsorption work and want to improve my theory so I can relate to complicated questions. 😊
