Size of study:
2160 women, 18-79 years of age

Summary
Higher vitamin D concentrations are associated with longer leukocyte telomere length. The difference in leukocyte telomere length between the highest and lowest tertiles of vitamin D concentrations was 107 base pairs, which is equivalent to 5 years of telomeric aging. In addition to being older biologically, the difference was further accentuated by increased concentrations of C-reactive protein, which is a measure of systemic inflammation.

The TeloYears test is not intended for screening, diagnosing, treating or preventing diseases or medical conditions. The TeloYears genetic test may indicate the possibility of identifying a rare telomere syndrome associated with extremely shorter or longer average telomere length (ATL). In these rare cases, further testing and consultation with a doctor to rule in or rule out a telomere syndrome is recommended. The test is available for individuals between the ages of 20 to 80 within the United States, except for the states of Maryland and New York. The information provided by the TeloYears test should not be used to replace medically appropriate screening tests recommended based upon actual age or other risk factors, nor should the information be used to make decisions about diagnosis or treatment of diseases or medical conditions. The Telomere Diagnostics lab is regulated under the Clinical Laboratory improvement Amendments of 1988 (CLIA) as qualified to perform high complexity clinical testing. The performance characteristics of this test were determined by Telomere Diagnostics. It has not been cleared or approved by the U.S. Food and Drug Administration.
