Blood Test Provides Highly Predictive Data on
10 Year All-Cause Mortality in Older Adults

In a February 2014 paper,1 scientists report a new inflammatory index comprised of just two proinflammatory cytokines that can be measured from blood samples and provide a highly predictive correlation with 10 year all-cause mortality in older adults. “Although all five inflammatory markers significantly predicted mortality, log IL-6 and log soluble tumor necrosis factor-alpha receptor 1 (sTNFR1) were the most predictive among the five.”1
