What is HealthTAV®?
Powered by TAT®
HealthTAV® is our telomere-measurement test based on TAT® (Telomere Analysis Technology), the world’s most accurate method to measure telomere length and multiple associated variables.
It reads individual telomeres in individual cells to deliver a precise picture of cellular health and optimize your healthspan and maximize your longevity.

Telomeric Biological Age
Who is it for?
Why telomere-based aging markers matter
HealthTAV® converts single-cell telomere information into a clear biological-age profile.
It is especially useful to establish a baseline and for longitudinal follow-up after lifestyle, supplementation or therapy—showing whether aging biology is accelerating or stabilizing.
As an objective blood test, HealthTAV® supports prevention programs and personalized medicine.

Graphic legend: MTL / 20th Percentile
Telomere shortening is uneven: most people have more short than long telomeres. For this reason, the median is more accurate and comparable than the average.

Biological age estimate
Derived from MTL and the short-telomere burden (P20) against our reference population; results are interpreted against an extensive population database to provide a snapshot of how old the body is at the genetic level.
Since telomeres shorten naturally throughout life, this biological age is not easily reversed. The goal is to slow down shortening and improve key markers such as Median Telomere Length (MTL) and the proportion of short telomeres through lifestyle and preventive strategies.

Frequently Asked Questions
What drives telomere length and shortening?
Telomeres vary by species and by genetics, environment, and lifestyle within a species.
They promote cellular senescence and are associated with age-related conditions: cardiovascular disease, neurodegeneration, multiple cancers (e.g., prostate, ovarian, lung), diabetes (type 1 & 2), and infertility.
Can I combine it with other biomarkers?
How can I help preserve telomeres and how is it measured?
How often should I repeat the test?
