Urine Albumin Test: The Earliest Kidney Damage Marker
What a urine albumin test measures and why it catches diabetic kidney disease early.
Last updated: 24/9/2026
Albumin is the main protein in blood. A urine albumin test detects tiny leaks into urine — often the earliest sign of kidney damage, before symptoms.
Who needs it
Everyone with diabetes or high blood pressure should have a urine albumin test at least yearly.
What results mean
Persistently raised albumin means kidney damage is beginning — and early treatment can slow it significantly.
Frequently Asked Questions
What is a normal albumin creatinine ratio?
Below 30 mg/g is generally normal. Your doctor interprets your exact value.
