Some time ago we had some discussions about wasted strips due to failure of method and I promised to report back on the test I have at my surgery. Had one yesterday so here goes. (2.7 by the way after a week of antibiotics).
I asked the phlebotomist how she did it and was amazed at what she told me. The blood does not go on top or underneath. She inserted the strip after stabbing my finger and then holding the machine in one hand and my hand in the other scraped the blood off by moving the strip over my finger from one side to the other. She explained that the strip has a tiny gap between top an bottom sections and the blood needed to get into this gap for the test. When I asked about dripping the blood on top she said it can get into the strip but it is not a fool proof way, which her method is. Now I understand why I thought you put the blood on the underside as that is what it looks like from my angle when she does it.
So people now you know. I hope that this helps some of you to stop wasting strips so often as reported.
