What Is a DNA Methylation Test?
A plain-language guide to DNA methylation, what a methylation test measures, and how to interpret its limits.

Short answer
A DNA methylation test measures chemical marks associated with how DNA is regulated. It can describe age-related and biological patterns, but it does not show that a single gene is simply on or off and it does not diagnose disease.
A regulation layer, not a rewrite
Your DNA sequence is the inherited text. Methylation is one of several systems that help cells regulate how that text is used. A useful analogy is a set of annotations—not a replacement instruction manual.
Patterns can vary by tissue, age, health, and exposure. That is why results need context rather than a universal supplement list.
What Kure does with the result
Kure reviews methylation patterns alongside inherited predispositions, symptoms, medications, conventional labs, and other diagnostics. The report helps organise questions and priorities; it does not replace clinical evaluation.
What this means at Kure
AgeCode is one layer of Signal-Based Medicine. We review inherited architecture and methylation patterns alongside current symptoms, history, medications, standard laboratory findings, and other diagnostics. A report supports a clinical conversation; it does not make the decision alone.
