For research purposes wouldn't it be nice to be able to do your own testosterone tests. I was reading and thinking, maybe is it possible to use ammonium sulfate to precipitate "bioavalible testosterone" from plasma. This is how i figure it would go.
Draw 1cc of blood in an insulin syringe, a makeshift centrifuge could be used to spin the needle as is, the plasma would then be expelled into a centerfuge tube containing a solution of water and ammonium sulfate. Centrifuge filter tubes to catch the solid testosterone. This can then be weighed with a ug accurate scale made from an analog voltmeter, ammeter, vu meter, whatever. The weight will not be mush more then an eyelash... that is what will make it hard. If a solvent extraction was possible it would be easier, as filters are usually trouble.
Thoughts?
