The Predictive Power of the Cystatin C-Creatinine Score in Assessing Frailty.

Summary: As people get older, doctors want to know who might become weak or sick. This study looked at health data and blood tests from over 3,600 older adults. They found that combining two common kidney tests—Cystatin C and Creatinine—creates a powerful new health score. This score is great at predicting who is at high risk of becoming frail or dying early. By using this simple test, doctors can spot people who need extra help and care much sooner!
