I have looked at the DIYBio groups on a number of occasions, and while they are fascinating it their own right, they aren't quite what I am interested in. DIYBio (as far as I can tell) is considerably more interested in DNA sequencing and genetics, whereas I am more interested in diagnostic tools for improving my quality and quantity of life.

An example of something I am interested in is: http://jenslabs.com/category/electronics/ketosis-detector/

but my more general question is: how can we do everything a standard blood panel does now, except do it extremely frequently (e.g. daily or hourly or even continuously) and noninvasively or as close as is feasible.

Of course, I know very little about the field, so this might all be the equivalent of "Hey guys, I know a little HTML and I was wondering if I could build a MMORPG..." posts on gamedev, but hey, gotta start somewhere. :D
