Aging
Naïve T-Cells
Immune cells that have not yet encountered an antigen — their decline is a hallmark of immune aging (immunosenescence).
Optimal Range
Age-adjusted percentile (higher = younger immune system)
Why It Matters
The decline of naïve T-cells and the accumulation of senescent T-cells is one of the most consistent features of immune aging. Low naïve T-cell counts impair your ability to respond to new infections and cancers.
