I have type 2 and am on metformin. I test every mourning after I get out of bed. I have been doubting my readings due to a strict diet, so have been testing 3 times at the same time and come up with 3 different readings that range about 40 pts apart from different fingers at the same time. This is my third meter but still same results. Is there a more accurate test or is this common? It's hard when its all over the board to nail down an accurate result.
