If we can narrow the scope of what to check down enough, I think we can
avoid having some huge nightmarish machine. I would suggest starting off
with measuring only a few parameters, then adding capabilities as science

My first concerns would be making it easy to use, reliable, and cheap.
Later we can add on comprehensiveness.

I would think also urine analysis, perhaps done spectrally or through a
gas chromatograph. No, even that sounds a bit much.

How about finding out what basically goes wrong -- i.e., what chemical
changes happen in blood, urine, etc. -- and developing simple solution
tests for those? In other words, mix 1cc of blood with the kit's blood test
solution A and depending on what color it changes, this tells you if blood
LDL levels are too high?

Something like this might prove marketable now.

I can imagine doing very simple tests, such as those of reaction time to
visual stimuli combined with a measurement of neurotransmitter levels...

This is not as glamorous as the other two you mention, but if we start
out with a simpler goal we might achieve it, market it, and move on to
some more complex/interesting.
