Why This Biomarker Matters

An elevated ratio suggests possible early kidney damage. Proteinuria is a key indicator of diabetic kidney disease and cardiovascular risk requiring intervention.

Overview

This urine test measures the ratio of albumin to globulin proteins. Albumin is normally filtered minimally by healthy kidneys, while globulin appears in urine in very small amounts. An elevated albumin-to-globulin ratio in urine may indicate early kidney damage or diabetes-related kidney disease. Proteinuria (excess urinary protein) is an early warning sign of kidney dysfunction and cardiovascular risk. Monitoring this ratio helps track kidney health and response to treatment for diabetes or hypertension.
