Kidney
Creatinine
Creatinine is produced by muscle metabolism at a relatively constant rate and filtered by the kidneys. Serum creatinine is used to estimate glomerular filtration rate (eGFR).
Levels can be influenced by muscle mass, diet, and supplements (creatine).
What It Measures
Serum creatinine concentration reflecting kidney filtration.
