Rishi Kumar—an anesthesiology resident—talks about the experience of going to the lab and doing his own type and cross-match (the thing we do to make sure you get matched blood products).
I think we need more of this in medical education. I think there could be an entire class (during 4th year would be a good spot) dedicated to laboratory medicine. Students would actually get to perform the tests we often flippant order without a second thought to the labor required to produce the result. Not only would we imbue respect for the tests, but we would learn some of their shortcomings and nuances to their execution.
