Scientists have discovered a simple blood test technique which can help to predict how long people will live.
They believe blood sample analysis can be used to forecast vulnerability to life-threatening illnesses and expected mortality.
The researchers base their claims on a study of genetic traits or “biomarkers” in a blood sample.
By analysing the biomarkers of nearly 5,000 adults, they were able to link a person’s biomarker patterns or “signatures” to healthy or unhealthy ageing.
Certain patterns were associated with different probabilities of life-threatening diseases like cancer, heart disease and type 2 diabetes.
The team from Boston University in the US say their findings could help save the lives of those more likely to fall ill.
Paola Sebastiani, the university’s professor of biostatics, says in her paper: “This analysis shows that various biomarker signatures exist.
