No more trips to the clinic for a urinalysis (perhaps). This seems like a great tool to share info with your doctor. Imagine getting your lab results in minutes and not hours or days.
I was jesting about not having to go to a clinic to do a drug test. Having this unit at home would make it to easy to cheat on a drug test.
It would be nice to share data with your doctor electronically without having to go wait in their office. The wonders of technology cease to amaze.
