Singapore, June 9 -- Researchers from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) have developed an improved biological ageing clock, LinAge2, that offers doctors a practical and more accurate way to assess how quickly a person is ageing, and what can be done to slow it down.

The new algorithm-powered tool builds on earlier clinical ageing clocks known as PCAge and LinAge. These older models, derived from blood and urine tests and health questionnaires, demonstrated strong predictive capability for long-term mortality and functional decline.

PCAge, in particular, outperformed standard cardiovascular risk scores and could forecast ageing trajectories well before the onset of disease. This approach...
