Albumin/Creatinine Ratio (ACR) Test Results
Albumin/Creatinine Ratio (ACR) Test Results
The ACR test evaluates kidney health and detects kidney damage signs. This test measures urine albumin (protein) compared to creatinine (waste product) levels. Medical teams use ACR values to check kidney function and guide treatment plans.
If you recently received your results back and need an explanation about what they mean, LabAnalyer can offer a specific breakdown.
ACR Test Purpose
ACR tests find and track kidney damage in patients with diabetes or high blood pressure.
Why Is Albumin Measured?
Albumin characteristics:
Blood protein type
Healthy kidneys block leakage
Urine presence signals damage
Measurement units: mg/L
Test sensitivity: high
Why Is Creatinine Measured?
Creatinine facts:
Muscle waste product
Kidney filtration marker
Constant daily production
Excretion rate stable
Reference standard use
Benefits of the ACR Test
Clinical uses:
Finds early damage
Monitors disease status
Shows treatment results
Predicts outcomes
Guides medical decisions
Normal vs Abnormal Ranges
ACR measurements use milligrams of albumin per gram of creatinine (mg/g).
Normal ACR Levels
Standard ranges:
Men: <17 mg/g
Women: <25 mg/g
General cutoff: <30 mg/g
Daily variation: ±5 mg/g
Lab differences: minimal
Elevated ACR Levels
Classification system:
Moderate increase:
Range: 30-300 mg/g
Called microalbuminuria
Early warning sign
Treatment trigger
Monthly monitoring
Severe increase:
Values: >300 mg/g
Called macroalbuminuria
Kidney damage marker
Medical urgency
Weekly monitoring
Factors Affecting ACR Results
Test variations from:
Exercise effects: 2-4 hours
Fluid status changes
Body temperature
Recent illness
Sample timing
Kidney Disease Markers
ACR tests reveal kidney status.
Detecting Early-Stage Kidney Disease
Early changes:
Albumin rise first
Normal GFR possible
Subtle symptoms
Treatment window
Prevention focus
Chronic Kidney Disease (CKD) Stages
Disease progression:
Stage 1-2:
ACR: 30-300 mg/g
GFR: >60 mL/min
Minimal symptoms
Early intervention
Lifestyle changes
Stage 3-5:
ACR: >300 mg/g
GFR: <60 mL/min
Clear symptoms
Medical treatment
Close monitoring
Complementary Tests
Multi-test approach:
GFR testing:
Filtration rate
Kidney function
Disease staging
Treatment guidance
Progress tracking
Blood markers:
Serum creatinine
Blood urea nitrogen
Electrolyte levels
Protein status
Mineral balance
Diabetes Monitoring
Diabetes affects kidney health.
Albuminuria in Diabetes

Value tracking
The ACR test measures kidney damage and guides treatment plans. Regular testing helps prevent complications and track disease changes. Medical teams use ACR values with other tests for complete care.
