Thanks Porco, I had a look for some information but didn't stumble across this AIC. Unfortunately it doesn't mention the peripheral blood stem cell doantion which needs the course of g-csf drug prior to donation.
I'd still prefer to use the peripheral method if possible but at least I know that I can't, I can donate bone marrow without much of a licencing problem. My wife, who is a practice nurse, would prefer me to go for the bone marrow donation as it doesn't involve drugs (other than the GA of course) but I don't fancy the GA or a couple of nights in hospital.
