BOSTON – A new blood test can predict a person's chance of living to 100 with up to 85 percent accuracy, U.S. scientists said Thursday.

Researchers from Boston University studied the DNA of 801 centenarians along with a control group of 914 healthy people of all ages and identified 281 genetic variants in the elderly group.

The genetic markers allowed the researchers to formulate a test to predict whether people would live beyond 100 with between 60 percent and 85 percent accuracy.

The test's accuracy increased with the age of the participant -- meaning the older the person taking the test, the more reliable the calculation of how long they will live.

As people who reach 100 generally do not experience age-related diseases until their mid-90s, scientists hope that isolating their genetic traits may help to find new treatments for diseases such as dementia and heart failure.

Dr. Thomas Perls, the study's lead author, said, "Further study of these genetic characteristics may yield a better understanding of the genetic and biological bases of delaying or escaping age-related diseases and achieving longer survival."

While the findings suggest that genetics play a much greater role in determining longevity than previously thought, the researchers stressed that healthy aging is still impacted by lifestyle factors, such as diet.

The study, published in the journal PLoS ONE, replaces research done by the same team in 2010 that was retracted from the journal Science due to problems with the analysis of the initial data.

Thursday's paper was independently reviewed by Yale University scientists and an additional data set of elderly participant with an average age of 107 was added.

I wish people would include a link to the paper when writing stories like this, or at least give the title of the paper.

Why the hell did I have to get born before the time when all fetuses are approved based on such criteria? :(

Very interesting. Hopefully some of this stuff materializes into something that actually helps people live longer and more healthy lives... Science is kind of in a rut... lool

When it comes, nothing will be able to save you.
Same goes for these blood tests.
They are good only for making useless progress

I think that the 'placebo effect' would strongly affect the outcome.
If the tests say you won't live till that long, you won't. If they say you will, then you will.
