my hemoglobin a1c always runs high — it's it's i've measured it as high as 5.8 the lowest i've ever had measured is 5.1 but any time i've measured it if i go and look at my because i've been wearing cgm for almost six years now if i go and check my a1c versus my trailing 90-day cgm it almost always suggests that the hemoglobin a1c is higher by 0.5 to 0.8
