Not to nitpick, but are you in the medical profession? Like a doctor or student? if you are, aren't you supposed to know those by heart? Although of course it would depend on your specialization. I wouldn't really expect a neurosurgeon to know what blood tests you need for syphilis, although it should be pretty basic that you need VDRL test.
Anyway, won't a simple notepad work? Like list down everything, then you can put it on your phone. Or a PDF reader and get an ebook that has that list.
