Along with estimated GFR, urine albumin measurement and reporting is critical to the early detection and treatment of chronic kidney disease. Issues with the standardization of urine albumin measurement and reporting exist, making it difficult for providers to effectively use test results to inform treatment decisions and monitor patients' kidney health.
Among these issues are:
- A variety of test options (albumin, albumin-to-creatinine ratio, etc.)
- Confusion about type of urine sample to collect (random, timed, overnight, or 24-hour)
- Nonstandardized urine albumin measurement procedures and lack of an international reference material
- Nonstandardized reporting units
- Arbitrary single cut-off value (30 mg/g) vs. specific cut-off values for gender, race, and age
