A new blood test can tell if your death is imminent. Would you want to know?
Finnish and Estonian researchers report that they have identified specific levels of four chemicals circulating in the blood that offer a reliable signal that death is near. The four harbingers of death can be readily detected in a blood sample, and are even predictive when seen in apparently healthy people. The study suggests that several potentially deadly conditions — including cancer and cardiovascular disease — may share origins that have been hidden in plain sight. If readily detectable physiological clues could warn of many dangerous conditions at once, the same blood test might enable an early death to be averted.
