Clinicians can assess the presence of albumin in the urine to diagnose and monitor the progress of CKD. The endpoint used is a measure of urine albumin expressed as a ratio of the creatinine content of the urine. This allows standardization of patient results over time, minimizing the impact that urine dilution (e.g., hydration status) may contribute.
This ratio is most commonly reported in units of mg/g. For example:
- Urine Albumin: 25 mg/L
- Urine Creatinine: 150 mg/dL (1.5 g/L)
- Albumin/Creatinine Ratio: 16.7 mg/g creatinine
