A Simple Blood Test Could Predict Your Odds of Living Longer With Surprising Accuracy

A Duke-led study suggests blood piRNAs may help predict two-year survival in adults 71 and older.

Six piRNAs identified from more than 1,200 blood samples predicted short-term survival with up to 86% accuracy.

The marker panel outperformed age and many standard health measures, and the result held up in an independent validation group.

Researchers say the minimally invasive approach could help flag higher-risk older adults earlier and guide preventive care.
