The kind you don't have to study for :) I saw my doctor yesterday and got some bloodwork done. We're checking my herpes zoster antibodies in case I need a booster, in the form of the shingles vaccine. Also a couple ruling-out-bad-but-treatable-things tests.
I test really well, actually. But now I'm grown-up and lazy so my favorite tests are the kind where I do nothing. Except curse that my best blood draw spot happens to be right below a valve in my vein.
