HbA1c sits inside the at-home panel I use, next to the rest of the metabolic set.

What I use for this Evidence: Moderate

Full transcript

HbA1c is your average blood glucose over the previous eight to twelve weeks — the single best one-shot picture of metabolic health for most adults. Under five point four percent is excellent metabolic flexibility. Five point seven to six point four is the pre-diabetic range, and that is the one to act on. Six point five or above is a diabetes diagnosis, which is a clinician conversation, not a protocol. Recheck every three to six months. agegen.ai. Generate your prime age! ~~ Mr. Age
