Question 82 of 433
Glycan age, “organ age,” and NAD level tests?
The short answer
SKIP for now. They are interesting research tools without proven uses.
Glycan tests read sugar molecules attached to antibodies, which track with inflammation. Organ-age tests estimate the age of individual organs from blood proteins. NAD tests have no validated normal range. Like the epigenetic clocks in Part 4, none has been shown to guide treatment that improves health. One study found that standard epigenetic clocks could differ by as much as nine years between two runs of the same blood sample.
