I just want to be able to gain an understanding of whats going on inside my body, that way I might be able to figure out the cause of the various strange things that happen me on drugs (i.e. on amphetamines I often abruptly start feeling like complete crap, and all sorts of physiological processes change) and when I'm off them. Lately something weird has been going on, I'm getting severe drowsiness, headaches, fevers and other miscellaneous symptoms like shortness of breath. If I take opioids at the moment they make me feel like shit, which is very unusual since they usually give me positive effects. Same goes for amphetamines.
I want to get a glucometer (well I already have one but ran out of strips) and an iron test kit so I can see if hypoglycemia or anemia are the cause of these weird symptoms I have right now. I think its pretty cool to be able to get an understanding of whats going on in your body, so I'd like to get more tests like this. For example, I want to check my testosterone cuz low testosterone could be the cause of my lethargy. I'd love to be able to check my levels of B vitamines but I'm guessing thats more complicated.
What about testing levels of your electrolytes i.e. Na+, K+, Ca2+, Cl- etc. That way you could check if they are imbalanced, then balance them if needs be. Are you sure there aren't any more of these cheap home tests (which don't need to be sent into a lab)? Electrolytes can't be that hard to test for can they? Maybe they could use strips with zeolites that trap atomic cations, then separate them based on their size.
Glucometer strips contain glucose oxidase which traps and oxidises glucose. Why couldn't they employ the same principle for other biomolecules? For example to detect epinephrine, to trap and deaminate the AA, then the device can detect the change in pH.
