Well, a couple of weeks ago I had my best ever hba1c since I was pregnant (my son is 31) and the pregnancy hba1c was accompanied by a drastic/life threatening loss of hypo awareness. I was surprised , since my cgm suggested my usual 50 ish, and I would have been delighted with a 48.
I went to see my consultant this week (first visit since 2020) and she agreed that my love hate relationship with lantus had got ridiculous (lots of night time hypos) and persuaded me to try a pump. Only problem, need to go through a lot of hoops in New Zealand if your hba1c is less than 53. The DNs suggested I use their machine for a quick fingerprick hba1c check, as it "reads high" (I kid you not).
The result came in at 53 so be prepared for a lot of posts from me on the insulin pump forum.
Still have no idea what my actual hba1c was but this just goes to show that there are times when 53 is better than 45 (at least in New Zealand)
