WebIn acutely ill individuals GFR often changes rapidly, and cystatin C tends to track this more accurately due to its shorter blood half-life. Muscle mass can also decline rather abruptly in the hospital, further confounding the relationship between GFR and creatinine. Overall, the optimal use of cystatin C among acutely hospitalized patients is ...
