- Kidney Functions
- Creatinine levels in urine are often paired with blood creatinine levels to calculate the creatinine clearance rate, which estimates how efficiently the kidneys are filtering waste.
- Muscle Metabolism
- Unusually high or low creatinine levels may reflect changes in muscle mass or activity.
- Hydration Status
- Creatinine concentration can indicate whether urine is overly diluted (low creatinine) or concentrated (high creatinine).
- Reference for other Biomarkers
- Creatinine is often used as a "normalizer" to correct for variations in urine concentration when analyzing other biomarkers.
