I would like to know if someone has tested Cystatin C.
I have no health issues other than higher creatinine which was at 1.95 last time and Cystatin C was 1.63. I got blood test now and creatinine is 1.85 and Cystatin C 1.46.
Thus I find that Cystatin c has dropped more than creatinine.
Any ideas on what do these values mean
