How practical is this?

Through capillary action this gadget creates a slight vacuum that pulls blood from capillaries though tiny channels in the skin into a small tube. The device collects 0.15 cubic centimeters of blood, which is enough to test for “cholesterol, infections, cancer cells, blood sugar and other conditions”.

Well, that quote was enough to put me off the whole idea. And bearing in mind how unrepresentative capillary samples can be I must admit I am rather sceptical about the whole thing.

But time will tell. It always does…
