They have something like the medical tricorder from Star Trek, that you can put near a diabetic's skin and get sugar levels without having to do a stick. Gotta like that.

They (doctors, hospitals) NOW have and routinely use sensors that clip onto a finger and, without a stick, monitor oxygen and/or carbon dioxide levels in the blood. I know that. I have a hazy sort-of-memory also that there is a similar sensor for blood sugar, but I'm not sure.
