I’ve often wondered why we don’t have simple home medical testing kits for the most common problems one is likely to have. Just do a simple blood or urine sample at home once a month, and then send it off to be analyzed for the 15 most common (or cheapest to test for) illnesses and you’re much more likely to catch something early. I would imagine legal liabilities are the likely culprit.
It would seem that they’re doing something like this in Japan.
I predict that this will be a condition of health insurance in the future.
