Why This Biomarker Matters

Creatine excretion reflects muscle mass and kidney function. Abnormal levels may indicate muscle disease, kidney dysfunction, or metabolic disorders affecting muscle health.

Understanding Your Results

Normal Range

0 – 1500 umol/(24.h)

Overview

Creatine is a compound produced by your muscles and released into urine. A 24-hour urine creatine test measures how much creatine your body is excreting, which reflects muscle metabolism and kidney function. Abnormal levels may indicate muscle disorders, kidney disease, or metabolic imbalances. This test is sometimes used to assess muscle health and validate the completeness of 24-hour urine collections for other tests.
