I'm really struggling to get enough of a drop of blood from fingertip. I wash my hands in hot water beforehand, I did try squeezing hard but then told this was a bad thing, I'm using the sides of my fingers, having to prick about six or seven times each time before I've got any blood, and because at the moment I've only got 10 lancets I'm re-using, is that ok? But I don't think that the reusing is the problem because tonight when I finally got success it was on about the fourth attempt. What I did in the end was use an elastic band round my finger like a little tourniquet. Is that ok?
