What does the Albumin-to-Creatinine Ratio test measure?

Q: Why is Albumin-to-Creatinine Ratio measured?

ACR is the preferred screening and monitoring test for albuminuria in chronic kidney disease, diabetes, and hypertension. It predicts progression to end-stage renal disease and independently forecasts cardiovascular morbidity and mortality. Guidelines recommend annual screening in diabetes and consider ACR part of cardiovascular-risk assessment in hypertension and metabolic syndrome.

Q: What is the reference range for Albumin-to-Creatinine Ratio?

The standard reference range for Albumin-to-Creatinine Ratio is Normal <30 mg/g; moderately increased albuminuria (formerly 'microalbuminuria') 30–300 mg/g; severely increased albuminuria (formerly 'macroalbuminuria') ≥300 mg/g.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Albumin-to-Creatinine Ratio (ACR) is a clinical biomarker used in kidney-renal assessment. The ACR normalises urinary albumin excretion to creatinine excretion, providing a dimensionless concentration-independent index that estimates 24-hour albumin loss from a spot specimen. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Normal <30 mg/g; moderately increased albuminuria (formerly 'microalbuminuria') 30–300 mg/g; severely increased albuminuria (formerly 'macroalbuminuria') ≥300 mg/g.

Functional medicine optimalKDIGO and diabetes guidelines define <30 mg/g as normal, 30–300 mg/g as moderately increased, and ≥300 mg/g as severely increased albuminuria.

What is Albumin-to-Creatinine Ratio?

The ACR normalises urinary albumin excretion to creatinine excretion, providing a dimensionless concentration-independent index that estimates 24-hour albumin loss from a spot specimen. Because creatinine excretion is relatively stable in an individual, the ratio reduces the confounding effect of variable urine concentration and hydration state.
