Creatinine – Creatinine is a waste product from normal muscle activity that healthy kidneys filter out steadily.
What Creatinine measures
Creatinine measures kidney filtration – it’s the basis for estimating your eGFR.
Typical ranges
Roughly 0.7-1.3 mg/dL for men and 0.6-1.1 mg/dL for women, varying with muscle mass and lab. Reference ranges differ between laboratories and by age and sex, so always read your result against the range printed on your own report.
What high results can mean
Can signal reduced kidney function.
What low results can mean
Can reflect low muscle mass; usually not a kidney concern.
How the test is done
A blood sample; used to calculate eGFR. At-home collection works well for this marker when the sample is processed by a certified lab.
