Your pee can tell you a lot about you. There's a variety of
things that should be in it, and a lot that shouldn't. Now, A
lot of those things are detectable by their absorbance
spectra. For example, urea has a nice characteristic UV
absorbance spectrum. If that absorbance is a little high,
urinal will discreetly tell you that you're a little
dehydrated. Ketone bodies and glucose both have IR
signatures. Similarly, these abnormal values in these areas
can be displayed on a little screen. Proteins have a pretty
strong absorbance in UV on account of their tryptophan
content... also, conductivity can give limited information
So, basically, display a range of parameters on your pee on
a little screen.

||Good idea but does the notification have to be discreet?
Loud klaxons and bright flashing lights in the wee hours
(get it?) would act as a deterrent to you ever allowing
yourself to become dehydrated plus, if startling enough,
provide an opportunity for a subsequent stool analysis.
||Hell throw in a drug screen and you're all set. +
||+ and a pregnancy test. (presumably for the women)
||Most drug screens and certainly pregnancy tests are
antibody based, and therefore a bit of a one-shot
deal. Not really amenable to significant throughput.
||Ever heard of the Google Toilet? (see link). It's a 5
year old joke, but very relevant to this idea.
