测量PiRNAs的血液测试预测,71岁以上成年人的寿命为76%,精确度为86%,高于传统健康指标。 A blood test measuring piRNAs predicts longevity in adults 71+ with 86% accuracy, outperforming traditional health markers.

根据Duke Health和明尼苏达大学2026年的一项研究,测量PiRNAs(一种小的RNA)的血检可以预测71岁及以上成年人是否至少再活两年,精确度最高达86%。 A blood test measuring piRNAs, a type of small RNA, can predict with up to 86% accuracy whether adults aged 71 and older will survive at least two more years, according to a 2026 study by Duke Health and the University of Minnesota. 研究人员对超过1 200个血样进行了分析,发现具体的PiRNA水平较低,与存活时间更长有关,超过传统健康标记。 Analyzing over 1,200 blood samples, researchers found lower levels of specific piRNAs linked to longer survival, outperforming traditional health markers. 调查结果在一个独立团体中得到验证,并在老龄化小组中公布,表明PiRNAs可以作为老龄化的生物指标。 The findings, validated in an independent group and published in Aging Cell, suggest piRNAs may serve as biological indicators of aging. 虽然他们的确切作用尚不清楚,但这次测试有一天可以帮助指导早期干预,以促进健康的老龄化。 While their exact role remains unclear, the test could one day help guide early interventions to promote healthy aging.
