We check pregnant patients' urine. Every. Single. Visit.
Well, some of our more stellar examples of better living through chemistry club (we have the president and the treasurer right now on our patient list) are paranoid about our intentions. I really just care about the protein and the glucose. But they are convinced we run drug screens every time we check their pee. (just as an aside, that would be too much work! plus, it's not CLIA-approved)
So yesterday, Ms. President of the Better Living Through Chemistry Club brought in her SON'S pee for us to test. It was still cold from being in her fridge!
