Liver enzymes, though he'll do that anyways I'm sure. Just smack him on the ass and say, "Good hustle." If he's anything like my doctor he'll just giggle and shuffle his way out the room.
well if he;s a good doc he'll test for a whole bunch of stuff.....from what you've said in ur last post the only other stuff i could concievably think he;d test for is -
alpha feto protein
gonadotrophin levels
and maybe bicarbonates
and im guessing he'd do your standard blood work up (FBC) and U+E's as well
having said that, he may not send off for stuff if he doesnt feel its necessary. i;d just ask him why he isnt testing for this stuff, especially if ur paying for it. with the swollen testicle AFP seems prudent just to be on the safe side
