The ratio of albumin to creatinine in a spot urine sample — the most sensitive marker of early kidney damage.
UACR normalizes albumin leak for urine concentration using creatinine, so a single spot sample works. 30-300 mg/g is moderately increased (A2) albuminuria; > 300 mg/g is severely increased (A3). Rising UACR predicts CKD progression and cardiovascular events; RAAS blockade and SGLT2 inhibitors lower it.
Albumin leaking into urine — the earliest and most important marker of kidney filter damage, measured by urine albumin-to-creatinine ratio (UACR).
Abnormal presence of protein in the urine, a key marker of kidney damage and the strongest predictor of CKD progression and cardiovascular risk.
A blood-pressure drug (e.g., ramipril, lisinopril, enalapril) that also protects the kidneys by reducing protein leakage.
Kidney damage caused by diabetes - the leading cause of kidney failure worldwide, driven by hyperfiltration, albuminuria, and progressive scarring.
