Do you donate blood? If you are getting a high score, from older red blood cells…
You could try donating blood. Then go in 3-4 days later and have your A1C tested.
A 3 for insulin is “KETO OPTIMAL” in my book. It’s where mine was, prior to my CIRS exposure.
And I was doing a lot of fasting. Zero Carb.
What does your CGM Say? Your finger sticks?
Based on what you said… I would argue you have older red blood cells, because they are living longer/healthier because of so much less glycation, so the turnover is slower…
Finally… How do you feel? (If I have a choice of “great test scores”, or “feeling amazing”, I will take the second… Now if it’s “feeling amazing”, and horrible/obvious signs of disease, bleeding gums, etc. etc. Then I would try to figure it out)
