Overview of the Urine Albumin/Creatinine Ratio Test
The Urine Albumin/Creatinine Ratio, commonly abbreviated to ACR, measures urinary Albumin relative to urinary Creatinine to identify small amounts of kidney protein leakage.
The test assesses 1 renal biomarker: Microalbumin (Urine).
Healthy kidneys normally keep most Albumin within the bloodstream.
When the glomerular filtration barrier becomes damaged, increasing amounts of Albumin can pass into urine.
This can occur before conventional blood kidney tests show a major abnormality.
ACR is particularly useful because it corrects urinary Albumin for the concentration of the urine.
A very dilute specimen can contain a lower Albumin concentration simply because more water is present.
Comparing Albumin with Creatinine reduces this variability and provides a more reliable estimate of Albumin loss.
Persistent elevation is an important marker of chronic kidney disease and cardiovascular risk.
ACR is routinely relevant in people with diabetes and hypertension.
It is also useful in established kidney disease and other conditions affecting the glomeruli.
One raised result does not automatically establish chronic kidney disease.
Exercise, fever, infection, significant Hyperglycaemia and acute illness can temporarily increase urinary Albumin.
Abnormal findings are therefore often confirmed on repeat testing.
ACR is different from a Protein/Creatinine Ratio.
ACR focuses specifically on Albumin and is particularly sensitive to lower levels of glomerular Albumin leakage.
What Does the Urine Albumin/Creatinine Ratio Test Check?
The test assesses urinary Albumin leakage relative to Creatinine concentration. This test measures 1 biomarker.
Microalbumin (Urine)
Measures low-level urinary Albumin and is used within the Albumin/Creatinine Ratio to identify early kidney filtration damage while accounting for urine concentration.
Who May Benefit From the Urine Albumin/Creatinine Ratio Test?
ACR testing is particularly useful for early kidney screening and long-term renal monitoring.
People with diabetes - ACR is an important marker for early diabetic kidney involvement.
People with high blood pressure - Hypertension can damage glomerular filtration over time.
People with chronic kidney disease - Albuminuria helps characterise disease severity and risk.
People with cardiovascular disease - Persistent Albuminuria is associated with increased cardiovascular risk.
People with an abnormal urine protein result - ACR can quantify lower-level Albumin leakage.
People with normal Creatinine but significant kidney-risk factors - Albuminuria can appear before eGFR declines.
People with a previous raised ACR - Repeat testing can determine whether the abnormality persists.
People requiring routine diabetic kidney screening - ACR is widely used for this purpose.
How to Prepare
A temporary increase can occur with infection, acute illness or strenuous exercise.
Unexpected elevation may therefore need repeat confirmation.
Symptoms and Reasons to Consider the Urine Albumin/Creatinine Ratio Test
Early Albuminuria usually causes no symptoms.
Diabetes requiring kidney surveillance - Early renal damage can be clinically silent.
Persistent high blood pressure - Hypertension is a major kidney-risk factor.
Previous urinary protein detection - Ratio testing provides more standardised assessment.
Known chronic kidney disease - ACR can contribute to staging and monitoring.
Cardiovascular disease with kidney-risk concerns - Albuminuria provides additional prognostic information.
A previously abnormal Microalbumin result - ACR can improve interpretation by correcting for urine concentration.
Very low urine output, severe swelling, visible blood in urine or rapidly worsening kidney function requires medical assessment.
Persistent rather than isolated Albuminuria is the clinically important finding.

Your authorised result is delivered securely and can be interpreted alongside Creatinine and eGFR.
When Will I Receive My Results?
The current London Blood Tests turnaround is approximately 1–2 days after laboratory receipt.
The Urine Albumin/Creatinine Ratio currently costs £118.
Routine renal biochemistry can generally be processed rapidly after the specimen arrives.
Understanding Your Results
An ACR below 3 mg/mmol is commonly classified as normal to mildly increased Albuminuria.
An ACR of approximately 3–30 mg/mmol represents moderately increased Albuminuria.
An ACR above 30 mg/mmol represents severely increased Albuminuria.
Classification still depends on clinical circumstances.
One abnormal result should usually be repeated before persistent Albuminuria is diagnosed, unless the clinical situation already establishes significant kidney disease.
A raised ACR can occur with diabetes, hypertension and several glomerular diseases.
The result should be interpreted alongside eGFR, Creatinine, blood pressure and medical history.
Why Book With London Blood Tests?
London Blood Tests provides private Urine ACR testing for sensitive kidney-risk assessment.
Detects early Albumin leakage - Kidney changes can appear before blood Creatinine becomes abnormal.
Corrects for urine concentration - Creatinine improves interpretation compared with Albumin concentration alone.
Important in diabetes monitoring - ACR is widely used to detect diabetic kidney involvement.
Relevant to hypertension - Persistent high blood pressure can damage kidney filtration.
Provides cardiovascular-risk information - Albuminuria is associated with wider vascular risk.
Simple urine collection - No blood draw is required for the test itself.
Fast laboratory turnaround - Results are expected approximately 1–2 days after laboratory receipt.
Clear pricing - The Urine Albumin/Creatinine Ratio test costs £118.
