A blood test may one day be able to predict your life expectancy, according to Yale University scientists.

Scientists are working on a test that measures a person’s “phenotypic age“. To develop the test, they analyzed data from more than ten thousand people over a thirty year period, looking at more than forty clinical measures ranging from lifestyle, to medical history, to cause of death, when relevant.

For every year a person’s phenotypic age was above their real age, their risk of dying rose.

The test was also able to differentiate healthy individuals and those who may have had problems missed during traditional screenings.

It’s unclear when and if the test will be rolled out to the general population, as more work is needed.

The preliminary work, which was not reviewed by a group of peers, is published in the biological science archive “bioRxiv“.
