Advanced glycation (AGEs)
Reads: Reduces sugar damage
You want them minimized: fewer AGEs mean suppler vessels and slower metabolic aging.
What this marker reads
Advanced glycation end-products — the sugar-damaged proteins that stiffen tissue and inflame the vessel wall.
No body publishes a range for this marker
No society, national study or large cohort publishes a reference interval for circulating advanced glycation end-products. Blood AGE testing is not one test — CML, pentosidine, MG-H1 and total fluorescent AGEs report on different scales — so no figure would be comparable to a laboratory report.
Your laboratory reads your result against its own assay, and this page does not do that for it. What is above is what a named body published and for whom; what is below is the machinery the marker reads and the formulas witnessed on it.
What moves it
Blood-sugar support raises it.
Brownlee 2001, Nature 414:813 — hyperglycemia raises AGE-precursor flux, a unifying mechanism of glucose toxicity. Mechanism, precisely: during sustained hyperglycemia glucose reacts non-enzymatically with amino groups of proteins, lipids and nucleic acids by the classical MAILLARD reaction — Schiff base, then AMADORI rearrangement, then oxidative modification (glycoxidation) — to yield AGEs. Uncontrolled hyperglycemia is named the principal aetiology of diabetic complications precisely because it produces AGEs. AGEs ACT by two separate routes: receptor-mediated signaling through RAGE, driving oxidative stress and inflammation; and receptor-independent cross-linking of structural proteins such as collagen, causing tissue stiffness and impaired compliance. Not diabetes-specific: AGEs are also implicated in rheumatoid arthritis, osteoporosis and aging. Metabolic memory — the caveat that changes the practical claim: the literature explicitly frames non-enzymatic glycation of proteins, lipids and nucleic acids as producing a persistent effect. AGEs accumulate preferentially in tissues with low protein turnover, particularly the extracellular matrix, which is why damage outlives the exposure. Restoring glucose control does not immediately unwind what has already been cross-linked.
