Blood test predicts premature aging

Researchers of the King College of London, United Kingdom, have developed a blood test that could predict how long a person is going to live, what their long-term health will be and whether they will be susceptible to premature aging.

According to the study published in the journal International Journal of Epidemiology, is blood test It allows the identification of 21 substances linked to premature aging, which can be detected in an analysis carried out even from birth.

According to the scientists, the results of their research could further refine the prognosis of adult health and the rate of aging of a person, from the moment they are born, to making a prediction of their future health.

After testing more than 6 thousand twins, this test is based on the detection of a metabolite called C-glyTrp, linked to premature aging, which functions as a chemical "fingerprint" that is configured in the womb and can be seen modified by the feeding of the mother during embryonic development.

Certain forms of the molecule are linked to a tendency to suffer premature aging and could be identified with a simple blood test that would help prevent the diseases of senescence, explain the authors of the study.

The research also showed that the gene that causes aging could be modified by epigenetics, a process by which environmental factors change or eliminate genes and alter their activity.

These changes can influence the metabolism throughout a person's life, which affects their susceptibility to diseases related to age or premature aging.

However, this is not the first or only research that aims to develop a test with these characteristics. Such is the case of the experiments carried out by the National Center for Oncological Research (CNIO) of Madrid, Spain.

This blood test measures the length of the telomeres, the regions of DNA located at the ends of the chromosomes that are responsible for cell division and the life time of a cell, considered one of the most accurate and important indicators of the speed of aging.
