The Telomere Test can determine [Telomere Length](/blog/274/) and put it in relation to an individual's age. However, there are major statistical errors in both the use of the mean Telomere Length and with % short Telomere Length testing. The data is accurate in determining the slope of the line for a population (i.e. linear regression plots), but the Concept of reverse extrapolation from the y-axis (Telomere Length in kb or % sort Telomeres in bottom Quartile) to the x-axis (i.e. patients Physical Age) is NOT valid! For a given age, there is a wide Range (and standard deviation) of normal mean Telomere Length and normal % short Telomere Length. This is why Live Length is given people such erroneous reports, e.g. an individual in his 30s, based on % short Telomere Length is actual 66 (even if it not a healhty 66 year and does not take TA-65 or Product B or Exercise or take fish oil, etc.).
The reason for the discrepancy is that there are many causes of Cellular Senescence besides shortened Telomeres.
