A team of researchers believes that they can predict if you’re aging too fast through a relatively simple blood test.
Your body’s main organs age at a different rate, and measuring these changes through a blood test could help predict illnesses and bodily decline, according to a new study published in Nature.
Why it matters: After analyzing blood plasma from over 5,000 people, the researchers found that around 20 percent of those over age 50 had one organ aging at an accelerated rate.
What they’re saying: A simple blood test to measure aging organs can help with “guiding therapeutic interventions well before clinical symptoms manifest,” said an accompanying statement.
How it works: When asked how old you are, odds are you will answer with your “chronological age,’ — a number that fails to tell the complete story. Aging begins at the molecular level, with hallmarks like telomere degradation and DNA damage. And once this damage reaches a certain threshold, changes can be seen in the mirror.
How accurate tests like these are is also something that has been met with skepticism. Companies won’t reveal how exactly their protocol works, but they do acknowledge how certain influencing factors may not be measured.
Think bigger: The longevity complex is gaining more ground — partly due to the millions being invested by people in companies and protocols that promise a longer lifespan. However, it also points toward how we misunderstand aging.
