What is this test?
This urine test looks for small amounts of albumin that can be an early sign of kidney damage, particularly in diabetes. The laboratory may report a concentration, timed excretion or a ratio to creatinine.
Why might it be ordered?
- For regular kidney screening in diabetes.
- To follow a previous increase in urine albumin.
What sample is needed?
A spot urine sample is commonly used, often first morning, but confirm whether the order requires a timed collection or albumin-to-creatinine ratio.
How should you prepare?
Avoid strenuous exercise before collection and report fever, urinary infection, menstruation, acute illness or very high glucose, which can temporarily raise urine albumin.
How should you understand the result?
A single raised result usually needs confirmation because albumin varies. Interpretation depends on whether the report is concentration, timed excretion or UACR.
