I don’t have any scientific backing for this but is it possible that getting blood from finger becomes harder over time?
I’ve recently done a lot of finger pricks over 10 a day because my sugar has been hard to control. I am finding that no blood comes out any more - well not easily. I’ve been using the accu chek soft clik. I feel the needle jab into my finger so it’s deep enough. And it’s a new needle so not blunt.
I’ve also noticed, when I switch to the microlet next lancing device that comes with the contour next one glucose monitor I have better luck getting blood out. I don’t know why.
