Albumin-to-Creatinine Ratio (ACR)

Urine_kidney Unit: mg/g Urine test

Gold standard for detecting early diabetic nephropathy

Also known as: ACR,Urine ACR

Reference Ranges

Clinical Reference 0.0 – 30.0 mg/g

Optimal Range 0.0 – 10.0 mg/g

30-300 = microalbuminuria; >300 = macroalbuminuria

Related Conditions

Diabetes High

Kidney Disease High

Food & Lifestyle Recommendations

🍎 Food Follow a kidney-friendly diet: limit sodium, moderate protein, plenty of vegetables Plant-dominant diets reduce ACR and slow CKD progression in clinical trials

🍎 Food Control blood sugar if diabetic — tight glucose control reduces ACR progression Each 1% HbA1c reduction reduces microalbuminuria risk by 25-30%

Evidence-Backed Supplements

When High

Omega 3 Tier A May Decrease

Moderate evidence; omega-3 fatty acids reduce albuminuria in diabetic nephropathy.

Fish oil (EPA+DHA) 1000–2000 mg EPA+DHA/day With meals

PMID 30019766 PMID 32114706 PMID 30480773
Vitamin D Tier A May Decrease

Moderate evidence; vitamin D supplementation may reduce ACR in CKD patients with deficiency.

Vitamin D3 (cholecalciferol) 1000–2000 IU/day Morning

Questions to Ask Your Doctor

What stage of kidney disease does my ACR indicate, and what can slow its progression? ACR 30-300 = microalbuminuria (early CKD); >300 = macroalbuminuria (established CKD).
