Hi John.
I'm O (whether I'm + or - I have no idea). I should probably know this kind of info, shouldn't I? The only reason I know I'm type O is from experiements in science class.
Anyway, I never have had elevated CRP, even in the worst of flares (probably due to being loaded on prednisone I'm told), but I'm not tested using ESR because I have funny shaped erythrocytes due to spherocytosis, another loverly genetic disorder I managed to get. Lucky me.
Hope you're doing well.
