this has gotta be achievable. tell you what I'm imagining

you prick your finger like you're doing a blood test for glucose, and you just dab the blood on some machine's sensor pad and you get estimates of estradiol and estrone and testosterone and so forth

or, lower-tech, semiquantitative analysis: you get some kind of color reaction and you compare colors to a chart, like you're using a pee strip

how does that strike people?

@Alyx a thing I would like to see as well

@lambdagrrl oh I've thought about how
