Sample

Blood draw or sample collection at a local center

This test measures albumin and creatinine in a single urine sample and reports an albumin-to-creatinine ratio. Albumin is a protein that normally stays in the blood; small amounts in urine can be an early sign of kidney damage. The creatinine portion corrects for how dilute or concentrated the sample is. Clinicians order it to screen for and monitor kidney involvement, often in people with diabetes or high blood pressure.

• Urine albumin A protein measured in urine; small amounts can signal early kidney changes.
• Urine creatinine Used to normalize the albumin measurement for urine concentration.
• Albumin-to-creatinine ratio A calculated value that adjusts urine albumin for sample concentration.

• People with diabetes or high blood pressure.
• Individuals with a family history of kidney disease.
• Those with swelling or other signs of kidney concern.
• People monitored for early kidney damage.
• Anyone with risk factors for chronic kidney disease.

• No fasting is required for a random urine collection.
• Provide a clean-catch midstream sample when possible.
• Stay normally hydrated unless told otherwise.
• Avoid heavy exercise and treat any infection before collection.
• Tell the provider about medications that affect the kidneys.

The albumin-to-creatinine ratio helps show whether urine albumin is elevated even when the sample is dilute or concentrated. A raised ratio can be associated with early kidney changes, especially when it persists on repeat testing. Temporary factors such as exercise or infection can also raise urine albumin. A single result does not establish a diagnosis. Discuss the findings with a healthcare provider.
