Peter Attia's average blood glucose, as measured by CGM, imputes an HbA1c between 4.5 and 5, despite his actual HbA1c running higher due to beta-thalassemia trait.

“my average blood glucose imputes that I would have an a1c between 4.5 and 5 that's sort of the range that I would live in”

“My A1C runs very high because I have this condition called beta thalassemia trait. So I have a bunch of these little, I think I talked about this in the podcast. Shit for blood is one of your nicknames. Yeah, Maddie used to call me shite for blood. Always in a Scottish accent, you got shite for blood. So my little shite blood cells live a long, long time. I mean, I have no idea, but it's clearly longer than 120 days. So my A1C is very high. The lowest A1C I've ever seen in myself is 5 .6 and the highest is 6 .0.”

“On CGM, when you take a highly calibrated, rigorous look, my average blood glucose imputes that I would have an A1C between 4 .5 and 5. That's sort of the range that I would live in. So that's a material difference.”
