I have a heart condition which seems to have mostly cleared itself up but since it could be life-threatening if it changed its mind, I have to go to the hospital and get a full checkup from like five different specialist doctors every ten years or so. They run like a dozen different tests run on me. Fun stuff except it usually costs thousands of dollars and insurance doesn't like to cover it because they think it's optional or something.

Also the last time they did this (about two years ago) I swear they took about half of my blood supply and sorted it into about twenty different vials; part-way into this my vision tunneled in and I got all light-headed and later my mom said I had no pulse. EXCITING!
