Yes, I didn't go back after getting my first hbA1c in 2016 of 50.
Although I went through some pretty intensive calorie deficit diet at the time which was also as it turns out lowish carb in nature. Over time I kinda slipped back into unhelpful ways of eating (for me.) I didn't get a hbA1c again until 2022, so six years later, among the reasons it took me so long to go back was I didn't have any follow up appointment to my initial A1c, the other was possible denial/I'll be fine I'm not
_that_ diabetic mindset, not looking after myself as much as I
could, and another was later on the pandemic when I started realising maybe I should be monitoring this a bit more.
I was surprised I was down to A1c of 45, which I maintained for a while, then that crept up a bit, but was keeping an eye on it, and making sure I was going to request tests regularly as I was in that limbo zone where they put no further action on my record/nothing got triggered to remind me. Although the last one I had this year was a shock to me because it had jumped up 19 points, but I know what the reasons were, and partially out of my control. this result being higher has actually motivated me (beyond my normal motivation) to do as much as I can to make sure, external circumstances aside, to get my 'high score' down.
Edit: seriously garbled run on sentences when I read back, looked fine at first
