Measuring telomeres

Find out how old your cells really are.

The analysis of critically short telomeres, as well as the comparison between biological and chronological age, can provide helpful insights into individual aging processes. They offer additional guidance to help you make more conscious and informed health and lifestyle decisions.

On this basis, lifestyle factors can be reflected upon more precisely and adjusted if necessary. Additionally, if medically indicated and under medical supervision, selected nutritional supplements or nutraceuticals can be incorporated into a holistic longevity concept.

With HealthTAV® from Life Length, telomere biology becomes measurable. The test analyzes telomeres at the single-cell level using EDTA whole blood and provides key metrics such as MTL, P20, telomere length distribution, and a telomere-based biological age assessment. As a result, HealthTAV® offers a data-driven addition for anyone looking to support their healthy aging or longevity approach with a more sound foundation.

The HealthTAV® test is performed using an EDTA whole blood sample. Life Length provides a shipping kit with instructions for medical professionals for this purpose. The sample is then analyzed in the laboratory at the single-cell level to create a differentiated picture of individual telomere biology.

Discover the telomere test

With its patented TAT® technology based on HT Q-FISH, Life Length offers highly specialized telomere analysis at the single-cell level. Through confocal high-content imaging and standardized evaluation, key parameters such as Median Telomere Length (MTL), telomere length percentiles, and the proportion of critically short telomeres can be precisely captured.

FAQ Telomere Measurement

How often should I have my telomeres measured?

We recommend that individuals interested in monitoring their telomere length repeat this measurement annually. Periods of six months can be considered if significant lifestyle changes have occurred.

How is it calculated?

Life Length determines biological age using a mathematical formula that takes the individual's chronological age group into account, which is then evaluated based on the telomere length result.

Why do I need to know my biological age?

First, it is an excellent indicator of overall general health.
Second, knowing our biological age allows us to gain a better understanding of the lifestyle habits that affect aging. It also gives us the opportunity to make appropriate changes and measure the results through periodic re-testing.
Third, Life Length’s Telomere Analysis Technology (TAT) will enable personalized medicine by allowing doctors to treat their patients while taking their biological age into account.

What are the factors that affect the length of my telomeres?

Genetic predispositions and lifestyle are the two most important factors influencing telomere length and the rate of telomere shortening.
Certain lifestyle habits have been strongly linked to long and short telomeres.
Examples include smoking, obesity, and psychological stress. These three factors increase oxidative stress and inflammatory responses, resulting in rapid telomere erosion.
Other factors such as eating habits, exercise, and sleep also tend to have an influence on biological aging.
Current therapies based on telomerase activation, e.g., TA-65® capsules, have been developed to achieve rejuvenation.
Measuring telomere length is necessary to determine whether these therapies effectively improve telomere length.

What is the relationship between biological and chronological age, and what can we learn from our telomeres?

Not all individuals age at the same rate, even if they have the same chronological age. Therefore, it is important to identify molecular markers (other than chronological age) that estimate the degree of aging of the organism.
This information is equally useful for health professionals and individuals to detect the premature development of age-related problems and to consider lifestyle changes (e.g., obesity and smoking have been shown to accelerate telomere attrition, while exercise and a good diet slow it down). We should follow our telomere dynamics over the years by benefiting from potential telomerase activators.
Multiple lines of evidence show that telomere length is a good indicator of the degree of aging of the organism.

When can I expect the results?
Sie erhalten die Ergebnisse innerhalb von 4 bis 6 Wochen nach Einsendung der Probe an Life Length und können dann einen Termin für ein Beratungsgespräch mit Life Length vereinbaren.
Where can I find the online questionnaire?

Please go to http://www.lifelength-questionnaire.com/ and use the login credentials provided in your test kit.

When must the blood sample be sent?
Proben können nur von Montag bis Mittwoch verschickt werden.Die Versandanweisungen finden Sie in den "Anweisungen", die dem Testkit beiliegen.Bitte beachten Sie auch den Laborschlusskalender von Life Length, der dem Testkit beiliegt, um die Einsendung von Proben an Feiertagen zu vermeiden.
Does the online questionnaire have to be filled out?

The online questionnaire is not mandatory, but we recommend filling it out in order to receive a more personalized results report.
The login details are provided on the "For Patients" label.
To ensure you receive your results report on time, it is important that you complete the questionnaire at approximately the same time your blood is drawn, or indicate on your test request form that you will not be completing the questionnaire.

How is the blood sample shipped?

Important: Shipping must be carried out within a temperature range of 2ºC to 8ºC.
For this reason, we provide a special kit and a gel pack, which must be frozen at least 24 hours before the blood collection in order to transport the blood while kept chilled.

What if I receive a "bad" result? What can I do?

The report provides detailed information on your total telomere length up to and including your 20th percentile, as well as a statistically estimated biological age.
Knowing that you have a low 20th percentile average is like knowing, for example, that you have high cholesterol levels, which are influenced by certain lifestyle choices.
We recommend professional medical advice to make changes that may allow you to slow down telomere attrition and potentially even lengthen telomeres, thereby slowing down biological aging.
For individuals with unusually short telomere length values, the result could be due to a traumatic event, illness, or other stressful events, which may temporarily affect the length of the telomeres reflected by the blood cells that were measured.
These individuals should repeat the measurement at an interval of 6 months, instead of once a year.
