Telomeres are sections of genetic material at the end of each chromosome. Telomere Testing consists of a simple blood test that can determine the length of one’s telomeres in relation to the their age. Age adjusted telomere length is the best technique to date to evaluate biological age. Consecutive evaluation of telomere length is an indicator of how rapidly one ages relative to a normal population. Therapies directed at slowing the loss of telomere length may slow aging and age-related diseases.
